DESCRIPTION:Title: Review of book "The universe in helium droplet" by G. Volovik\nb
y Krzysztof Pomorski (University College Dublin) as part of QM Foundations
& Nature of Time seminar\n\n\nAbstract\nThere are fundamental relations b
etween three vast areas of physics: particle physics\, cosmology\, and con
densed matter physics. The fundamental links between the first two areas
— in other words\, between micro- and macro-worlds — have been well es
tablished. There is a unified system of laws governing the scales from sub
atomic particles to the cosmos and this principle is widely exploited in t
he description of the physics of the early universe. This book aims to est
ablish and define the connection of these two fields with condensed matter
physics. According to the modern view\, elementary particles (electrons\,
neutrinos\, quarks\, etc.) are excitations of a more fundamental medium c
alled the quantum vacuum. This is the new ‘aether’ of the 21st century
. Electromagnetism\, gravity\, and the fields transferring weak and strong
interactions all represent different types of the collective motion of th
e quantum vacuum. Among the existing condensed matter systems\, a quantum
liquid called superfluid 3He-A most closely represents the quantum vacuum.
Its quasiparticles are very similar to the elementary particles\, while t
he collective modes are analogues of photons and gravitons. The fundamenta
l laws of physics\, such as the laws of relativity (Lorentz invariance) an
d gauge invariance\, arise when the temperature of the quantum liquid decr
eases. \n\nBook: http://www.issp.ac.ru/ebooks/books/open/The_Universe_in_a

DESCRIPTION:Title: From Braids to Knots\; Topological features in Solar Magnetic Fields
– and beyond…\nby Ilan Roth (Berkeley) as part of QM Foundations
& Nature of Time seminar\n\n\nAbstract\nThe generally accepted structure o
f magnetic fields depicts them as field lines in $R^3$ with curvature\, ro
tation and wiggles\, satisfying $\\nabla\\cdot B=0$. Their observed config
uration allows us to implement the powerful topological methods\, opening
a new venue for an interpretation of various solar\, interplanetary and as
trophysical phenomena. Direct imaging of the coronal fields pinpoints to t
heir braiding structure\, large solar wind field reversal (switchback) and
intermittent fading of energetic flare ions suggest that coronal braided
field may have been carried by the solar wind. The interconnection between
the mathematical braids and knots is applied to the topologically non-tri
vial magnetized structures and their dynamics\, from solar corona and the
interplanetary medium to the astrophysical Herbig – Haro jets. The topol
ogical invariants attached to a given knot/braid become the crucial factor
in the evolution and interpretation of the phenomena in space. The method
s involved cover classical as well as analogues of quantum procedures. The
analysis results in conjectures regarding (i) stability of coronal magnet
ic loops under large oscillations\, (ii) their evolution through successiv
e emergence/decay of heated magnetic braids\, (iii) their morphism into th
e solar wind knotty structures and (iv) large scale narrow jets emitted in
star-forming regions. These conjectures may contribute significantly to t
he understanding of physical processes in the lab and in solar/astrophysic
al medium\, particularly in the dynamo produced magnetic structures as obs
erved by Parker Solar Probe.\n

pace-time. This model is related to Dirac monopoles\, one can see it as a
generalisation of the Sine-Gordon model from 1D to 3D\, or a modification
of the Skyrme model. Starting from a Lagrangian\, the intention of the mod
el is to provide a geometrical description of electromagnetic phenomena. T
he model has three topological quantum numbers which can be compared to th
e properties of charge\, spin and photon number. We discuss stable soliton
ic solutions and compare them to the properties of electrons and photons.\

eturn only integer charges (as in nature) by interpreting EM field as curv
ature of some e.g. vector field\, this way counting winding number (topolo
gical charge) using Gauss-Bonnet theorem as Gauss law (Faber’s model). I
will lightly introduce it and would like to discuss if we could expand it
to a field which excitations (e.g. topological) agree with the entire par
ticle physics\, could be effectively described by something close to the S
tandard Model. \n\nKind of superfuid biaxial nematic: 3 distinguishable ax
es in every point (using tensor field instead of molecules) seems quite pr
omising here. They can form hedgehog configuration with one of 3 axes\, ge
tting 3 leptons (as spatial dimensions)\, trying to align the second axis
for it we cannot do it due to the hairy ball theorem (no naked charges –
leptons need magnetic dipoles)\, then baryon-like configurations enforcin
g some positive charge: needed to be compensated in neutron (hence it is h
eavier than proton)\, charge is shared in deuteron for binding (leading to
observed electric quadrupole moment).\n

DESCRIPTION:Title: In memoriam: Yves Couder\nby Robert Brady (Cambridge) as part of
QM Foundations & Nature of Time seminar\n\n\nAbstract\nYves Couder died o
n 2 April 2019. He showed how to make droplets of oil bounce on an oil sur
face\, spawning a renewed interest in the net forces between oscillating s
ystems. Bouncing droplets are governed by the ordinary equations of Newton
ian mechanics\, yet experimentally their motion mimics the known equations
of special relativity\, electromagnetism\, and quantum mechanics. I will
show why this is the case\, in an idealised system where the pumping accel
eration can be neglected. I will then briefly discuss my ongoing research
in a related system in superfluid helium\, where pumping is superfluous an
d the predictions may be tested against experiment.\n\nIn order to maintai
n your interest\, and to pay respect to Yves\, I will give an interpretati
on of his work which is controversial. If his results had been known 100 y
ears ago\, they would probably have changed the debate\, from 1905 to 1922
\, between Einstein and Lorentz on how to interpret the equations of speci
al relativity.\n

many models of physics\, like unitary evolution in quantum mechanics\, or
Lagrangian formalism we use from classical mechanics\, electromagnetism\,
up to general relativity and quantum field theories. However\, this symmet
ry is quite nonintuitive\, very difficult to really accept – mainly due
to thermodynamical counterarguments. \nLet us try to discuss these argumen

dding more is welcomed)\, for example: Wheeler’s\, delayed choice quantu
m eraser (DCQE)\, “asking photons where they have been”\, “photonic
quantum routers”\, Shor algorithm as more sophisticated DCQE\, also: And

DESCRIPTION:Title: Nuclei as Skyrmions\nby Christopher Halcrow (Leeds) as part of
QM Foundations & Nature of Time seminar\n\n\nAbstract\nIn standard models
of nuclear physics\, nuclei are described as point particles with spin and
isospin degrees of freedom. The baryon number (the number of protons plus
the number of neutrons) is conserved in nuclear interactions - this fact
is usually put in “by hand”. In contrast\, the Skyrme model describes
nuclei as topological solitons. The baryon number is conserved due to a to
pological invariant of the theory while spin and isospin appear as quantis
ed isometries of the system. This talk is in two parts: first\, I will try
and convince you that the Skyrme model is a reasonable model of nuclear p
hysics. It reproduces several known phenomena: nuclear clustering\, isospi
n symmetry and rotational bands in energy spectra. I will then show that t
he Skyrme model is very different than standard nuclear models: the notion
of position breaks down\, the Deuteron is a torus and novel scatterings c
an take place. These surprising facts can give new explanations for some n
uclear properties. For instance\, the existence of a toroidal Skyrmion exp
lains the attractive spin-orbit force in the nucleon-nucleon interaction a
s shown recently in arXiv:2007.01304. I will explain this phenomena assumi
ng no background knowledge of Skyrmions or nuclear physics.\n

DESCRIPTION:Title: Maximal Entropy Random Walk: repairing diffusion-QM disagreement\nby Jarek Duda (Jagiellonian University) as part of QM Foundations & Nat
ure of Time seminar\n\n\nAbstract\nConsidering diffusion or chaos in [0\,1
] range leads to uniform stationary probability distribution rho=1. In con
trast\, QM predicts localized rho~sin^2 there. This disagreement is crucia
l e.g. for semiconductors – standard diffusion would predict nearly unif
orm electron distribution\, allowing them to flow – incorrectly expectin
g it to be a conductor. In contrast\, QM predicts strong e.g. Anderson loc
alization preventing conductance.\n\nMaximal Entropy Random Walk (MERW) al
lows to understand and repair this disagreement - turns out that standard
random walk often only approximates the (Jaynes) principle of maximal entr
opy\, which is crucial for statistical physics models – MERW is the most
random among random walk\, thanks of it leading to stationary probability
distribution exactly as quantum ground state – with localization proper
ty. In contrast to standard random walk\, MERW is also scale-free\, time s
ymmetric and nonlocal. It also has many other applications (~160 citations

violent fluctuations are experienced by an electromagnetic charged extende
d particle when it is perturbed from its rest state. The feedback interact
ion of Coulombian and radiative fields among different charged parts of th
e particle makes uniform motion unstable. Then\, we show that radiative fi

triggering a self-oscillation. Finally\, we compute the self-potential\, w
hich in addition to rest and kinetic energy\, gives rise to a new contribu

contribution to self-energy produces a symmetry breaking of the Lorentz g

lewski (AGH) as part of QM Foundations & Nature of Time seminar\n\n\nAbstr
act\nWe show that quaternion quantum mechanics has well-founded mathematic
al roots and can be derived from the model of the elastic continuum by Fre
nch mathematician Augustin Cauchy\, i.e.\, it can be regarded as represent
ing the physical reality of elastic continuum. Starting from the Cauchy th
eory (classical balance equations for isotropic Cauchy-elastic material) a
nd using the Hamilton quaternion algebra\, we present a rigorous derivatio
n of the quaternion form of the non- and relativistic wave equations. The
family of the wave equations and the Poisson equation are a straightforwar
d consequence of the quaternion representation of the Cauchy model of the
elastic continuum. This is the most general kind of quantum mechanics poss
essing the same kind of calculus of assertions as conventional quantum mec
hanics. The problem of the Schrödinger equation\, where imaginary ‘i’
should emerge\, is solved. This interpretation is a serious attempt to de
scribe the ontology of quantum mechanics\, and demonstrates that\, besides
Bohmian mechanics\, the complete ontological interpretations of quantum t
heory exists. The model can be generalized and falsified. To ensure this t
heory to be true\, we specified problems\, allowing exposing its falsity.\

DESCRIPTION:Title: Hidden fields preclude the demonstration of Bell-type theorem\n
by Álvaro García López (URJC) as part of QM Foundations & Nature of Tim
e seminar\n\n\nAbstract\nWe demonstrate that classical local field theorie
s can violate Bell’s theorem. To this end\, we\nargue that the physical
magnitudes appearing in such theories correspond to hidden fields of dynam
ical nature. This requires reconsidering Bell’s proof in terms of random
fields\, what prevents the expression of the correlation integral as a sp
acetime-independent variable. Then\, taking into account that the probabil
ity distribution evolves in time\, we show that the spin-correlation canno
t be expressed in terms of a probability density defined on initial data\,
which is independent of the measurement process. Finally\, we derive a ne
w inequality that is not violated by quantum correlation functions of enta
ngled spin pairs. Following recent results\, we propose that Maxwell’s c
lassical electromagnetism and its general covariant formulation might be t

-range e.g. Coulomb-like interactions for topological defects in liquid cr
ystals\, suggesting investigation how far can we take this resemblance wit
h particle physics. I will discuss postulating skyrmion-like Lagrangian to
get electromagnetism for their effective dynamics\, interpreting filed cu
rvature as electric field - making Gauss law count (quantized) topological
charge. For biaxial nematic - with 3 distinguished axes\, hedgehogs of on
e of 3 axes are different mass realizations of the same topological charge
- resembling 3 leptons. Further baryon-like topological structures requir
e charge\, which has to be compensated for neutron - suggesting why it is
heavier than proton. For analog of quantum phase there is derived Klein-Go

DESCRIPTION:Title: Quantum nonlocality: how does nature do it?\nby Marian Kupczyń
ski (UQO) as part of QM Foundations & Nature of Time seminar\n\n\nAbstract
\nLocal realistic and stochastic hidden variable models define experimenta
l protocols\, which are inconsistent with experimental protocols used in r
eal Bell Tests. Therefore\, it is not surprising that they fail to describ
e correctly the experimental data. In 2009 Nicholas Gisin claimed in Scien
ce\, that quantum correlations come from outside the space-time due to the
quantum magic. Since we do not believe in magic\, we propose a locally ca
usal explanation of these correlations. Neither super-determinism nor retr
o- causality is needed\, nor is experimenter’s freedom of choice (EFO) c
ompromised. In our contextual model\, setting dependent variables describi
ng measuring instruments are correctly introduced. Outcomes are predetermi
ned both by instrument variables and variables describing incoming correla
ted signals at the moment of the measurement. There does not exist a joint
probability distribution of variables describing all the possible setting
s\, thus Bell inequalities may not be derived. In this talk\, based on th
e articles listed below\, we also explain in detail why the assumption cal
led free choice-no conspiracy-measurement independence has nothing to do w
ith EFO and should be rather called noncontextuality assumption. The viola
tion of Bell inequalities neither implies the nonlocality of Nature nor th
e violation of EFO. It only confirms the contextuality of some observable
s in quantum domain and that outcomes are not predetermined before the exp
eriment is done.\n

DESCRIPTION:Title: Quantum superposition of thermodynamic evolutions with opposing tim
e's arrows\nby Giulia Rubino (Bristol) as part of QM Foundations & Nat
ure of Time seminar\n\n\nAbstract\nMicroscopic physical laws are time-symm
etric\, hence\, a priori there exists no preferential temporal direction.
However\, the second law of thermodynamics allows one to associate the "fo
rward'' temporal direction to a positive variation of the total entropy pr
oduced in a thermodynamic process\, and a negative variation with its "tim
e-reversal'' counterpart. This definition of a temporal axis is normally c
onsidered to apply in both classical and quantum contexts. Yet\, quantum p
hysics admits also superpositions between forward and time-reversal proces
ses\, whereby the thermodynamic arrow of time becomes quantum-mechanically
undefined. In this talk\, I will show that a definite thermodynamic time'
s arrow can be restored by a quantum measurement of entropy production\, w
hich effectively projects such superpositions onto the forward (time-rever
sal) time-direction when large positive (negative) values are measured. Re
markably\, for small values (of the order of plus or minus one)\, the ampl
itudes of forward and time-reversal processes can interfere\, giving rise
to entropy-production distributions featuring a more or less reversible pr
ocess than either of the two components individually\, or any classical mi
xture thereof.\n

re of Time seminar\n\n\nAbstract\nMax Planck famously introduced the notio
n of discretised packets of energy\, quanta\, thus kickstarting the develo
pment of our most successful theory of physics\, replacing classical theor
ies in which energy varies continuously. Despite its success\, however\, t
he concepts of reality and local causality are deeply problematic in quant
um mechanics. Such problems may lie at the heart of why it has been so dif
ficult to synthesise quantum and gravitational physics. \nMotivated by the
se issues\, we apply Planck’s discretisation insight again\, but this ti
me to the continuum of quantum mechanics’ state space - complex Hilbert
Space. A particular discretisation is discussed - one which draws on numbe
r theoretic properties of trigonometric functions. This leads to a model o
f quantum physics which is necessarily superdeterministic in character\, t
hat is to say violates the Statistical Independence assumption in Bell’s
Theorem. Because of this\, the model does not need to invoke concepts of
indefinite reality or nonlocality to explain the violation of Bell’s ine
quality\n

e–particle duality\nby Donald C. Chang (HKUST) as part of QM Foundat
ions & Nature of Time seminar\n\n\nAbstract\nA well-known mystery in quant
um mechanics is wave–particle duality: Is an electron a point mass or a
physical wave? What is the physical meaning of its wave function? About a
hundred years ago\, there was a famous debate between Bohr and Einstein on
this topic. Their question is still open today. This talk reviews a new t
heoretical framework to address this problem. We hypothesize that both pho
tons and electrons are quantized excitation waves of the vacuum\, the phys
ical properties of which can be modeled based on the Maxwell theory. Using
the method of Helmholtz decomposition\, one can show that the wave functi
on of the particle is associated with an electric vector potential called
“ Z”\, which plays the role of basic field for the excitation wave. Us
ing this framework\, the quantum wave equations can be derived based on a
quantization of the Maxwell theory. This work suggests that\, the quantum
wave function truly represents a physical wave\; the wave packet looks lik
e a “particle” only in the macroscopic view. Because the vacuum excita
tion obeys the principle of all-or-none\, the probability of detecting thi
s “particle” is related to the wave function as suggested in the Copen
hagen interpretation\n

periment\, featuring a geometry with a rotating Foucault mirror that teste
d this background field hypothesis by removing / gating said background in

cannot be due to a traveling (including superluminal) waves. This experime

DESCRIPTION:Title: A Quantum Vacuum Model Unites an Electron’s Gravitational and Ele

of Time seminar\n\n\nAbstract\nWhen physicists attempt to create a model
of a fundamental particle\, the immediate objective is to have the model m
atch the particle’s known properties. However\, for the model to be cons
idered “useful”\, it must ultimately make correct predictions that adv
ance science. This presentation is about an electron model that went beyon
d achieving an electron’s known properties and generated correct predict
ions.\n\nThe original objective was to match an electron’s wave-particle
and point particle properties. However\, the model unexpectantly also gen
erated an electron’s gravitational and electromagnetic forces. Most surp
rising\, the model predicted these forces are related through a nonlinear
effect incorporating an electron’s wave properties. For example\, gravit
ational and electrostatic force equations between two electrons are stated
using the electron’s strain amplitude raised to two different powers. T
hese insights reveal the underlying physics of how an electron creates bot
h a gravitational field and an electric field.\n\nThe seminar will start w
ith a description of the assumed quantum vacuum model. John Wheeler’s
“quantum foam” model is analyzed and expanded to include the calculate
d impedance of spacetime and the bulk modulus of spacetime. The electron m
odel must achieve an electron’s de Broglie wave characteristics. This re
quirement dictates the electron model must be a wave with Planck length am
plitude that is rotating at an electron’s Compton frequency with ħ/2 an
gular momentum. Besides subjects covered in the title paper\, electrical c
harge\, electric fields\, and photons will also be discussed.\n

DESCRIPTION:Title: Time-Crystal Model of the Electron Spin\nby Mario G. Silveirinh
a (ULisboa) as part of QM Foundations & Nature of Time seminar\n\n\nAbstra
ct\nThe time-crystal concept was originally introduced by Frank Wilczek [1
] and relates to systems with a spontaneously broken time-translational sy
mmetry\, such that the ground-state evolves periodically in time\, not wit
hstanding the equations of motion are invariant under arbitrary time-trans
lations (i.e.\, do not depend on the time origin). Thus\, the ground state
of a time-crystal is some sort of “perpetuum mobile”. The time-crysta
l idea was originally introduced in the context quantum many-body systems.
\nIt is natural to wonder if non-driven classical time-crystals may natur
ally occur in nature and if they can have a role in the description of phy
sical reality. In this talk\, I will show that a hypothetical classical ma
ssless particle has forcibly a time-crystal (non-driven) dynamics characte
rized by a spontaneous time symmetry breaking that originates a spin angul
ar momentum. I will show that a time-crystal particle is formed by two ins
eparable components: a massive-component that behaves as a classical parti
cle and a wave-component that whirls around the “particle” and generat
es the spin and an intrinsic angular momentum. The spin vector is parallel
to the binormal of the velocity trajectory and is the spatial component o
f a 4-vector. The trajectory of the particle is fully controlled by the tr
ajectory of the wave\, reminiscent of the pilot-wave theory of de Broglie
and Bohm. Furthermore\, in the proposed framework the “mass” is an eme
rgent property\, in the sense that it originates from the fact that the ce
nter of mass frame speed is necessarily less than c. The trajectory of a t
ime-crystal particle is controlled by a dynamical least action principle.
The massless-component dynamically probes the nearby space and the particl
e moves on average towards the direction of space that minimizes an action
integral.\nInterestingly\, the proposed model predicts the precession of
the spin vector about a static magnetic field\, and most remarkably it sug
gests that the mismatch between the spin precession frequency omega_s and
the cyclotron frequency omega_c –which is at the origin of the famous an
omalous magnetic moment – is a manifestation of the electromagnetic self
-energy. The time-crystal model pr edicts that the difference between omeg
a_s and omega_c results in an axial oscillatory motion\, which is consiste
nt with the experiment typically used to measure the anomalous magnetic mo
ment.\n

n\nAbstract\nI provide an overview of the transactional formulation of qua

this formulation\, the basic field interaction is time symmetric\, corresp
onding to virtual photons. This interaction is an unmediated\, direct conn
ection between charges\, which challenges our usual preference for localit
y. However\, the interaction can be elevated\, via a form of temporal symm
etry breaking\, to the local\, causal transfer of a real photon from an em
itter to an absorber. This constitutes a microscopic basis for the emergen

Foundations & Nature of Time seminar\n\n\nAbstract\nLight emitted from ato
ms during transitions of electrons from higher to lower discrete states ha
s the form of photons carrying energy and angular momentum. The paper cons
iders the process of emission of a single photon from the hydrogen atom by
using quantum theory and Maxwell's equations. The electric and magnetic f
ields of a photon arise from the time-dependent quantum probability densit
ies of the orbit and the spin current. This paper is an extension of the s
emi-classical description of photon emission published by the author earli
er in 1999. In the semi-classical approach the Coulomb force and a radiati
on resistance force have been taken into account to get time dependent emi
ssion of the photon. In both the quantum and semi-classical cases the tran
sition takes place within a time interval equal to one period of the photo
n's wave. The creation of a one-wavelength-long photon is supported by the
results of experiments using ultra-fast (ultra-short) laser pulses to gen
erate excited atoms\, which emit light pulses shorter than two photon wave
lengths.\n

part of QM Foundations & Nature of Time seminar\n\n\nAbstract\nGravitomagn
etic equations result from applying quaternion differential operators to t
he energy-momentum tensor written in the quaternion basis. These equations
are similar to Maxwell’s EM equations. They are parent ones generating
a series of equations describing the real physical processes. The vorticit
y equation gives solutions of vortices with nonzero vortex cores and infin
ite lifetime. The Hamilton-Jacobi equation loaded by the quantum potential
opens the hydrodynamic approach on the fermionic fields. In the relativis
tic limit\, this equation (together with the continuity one) underlies fer
mionic fields leading to the emergence of the Dirac equation. Analysis of
its solutions discloses the existence of the paired Majorana fermions havi
ng integer spins 1 or 0 as\, for example\, ortho- and para- hydrogens. On
e more solution of the Dirac equation leads to the existence of the partic
le-antiparticle pair.\nThe electron-positron pairs ordered into a macrosco
pic coherent Bose-Einstein condensate give a simple example of the existen
ce of Wilczek's time crystals. The pairs of proton-antiprotons\, loaded by
accompanying electron-positron buffers\, can pose long-lived ordered quan
tum objects. These objects representing the Bose-Einstein condensate look
like Wilczek's time crystals as well.\nThese macroscopic coherent ensembl

DESCRIPTION:Title: Liquid crystals as a playground of topological defects\nby Samo
Kralj (University of Maribor) as part of QM Foundations & Nature of Time
seminar\n\n\nAbstract\nPhysical fields might be fundamental constituents o
f nature. Furthermore\, topological defects in relevant physical fields mi
ght play the role of fundamental particles as first demonstrated by Skyrm
y [1]. He introduced topologically protected solitons (referred to as skyr
mions) as candidates for mesons and baryons. Therefore\, one could explain
all natural complexity from the viewpoint of TDs and their assemblies. \n
Liquid crystals (LCs) are particularly adequate to study TDs and related t
opological phenomena. They exhibit diverse qualitatively different TDs in
form of point\, line\, wall\, and texture configurations. In LCs different
assemblies of TDs could be relatively easily created\, stabilized\, manip
ulated\, and observed (e.g.\, using polarizing microscopy). \nIn the lect
ure\, we will present our studies of different TDs in orientationally orde
red LCs that might be analogs of fundamental excitations in nature the be
havior of which is still not understood. We demonstrate that geometrical c
urvature [2] is the mean generic formation and TD stabilization mechanism.
We show that the topology of torus stabilizes “chargeless” TDs [3] w
hich might play the role of neutrinos. In LCs they form an elastic ribbon-
like structure that embeds the toroidally shaped LC-immersed colloidal par
ticle. Furthermore\, we present the formation and stabilization mechanism
of merons (skyrmion family members) and their condensation in crystal-like
configurations. In pour experiments\, we made their structural details an
d dynamics experimentally accessible by forcing the LC structure close to
a critical point\, in which the relevant order parameter field correlation
length and relaxation time diverge. These quantities dominate the charact
eristic linear size of the defect core structure and its dynamic features.
In particular\, we show how TDs mediate temperature-driven order-disorder
phase transition in chiral LCs.\n \n\n[1] T. H. R. Skyrme\, A uni

DESCRIPTION:Title: A new relativistic quantum mechanics\nby John G. Williamson (Un
iversity of Glasgow) as part of QM Foundations & Nature of Time seminar\n\
n\nAbstract\nDirac's theory has been the "gold standard" of relativistic q
uantum mechanics (RQM) for more than ninety years. During that time the qu
antum mechanics used in the imagining and engineering of quantum devices h
as been in the realm of\, almost exclusively\, the non-relativistic Schro
ëdinger theory using complex wave-functions.\n\nThe merely complex is\, h
owever\, too simple to properly represent covariant\, relativistic wave-fu
nctions. Furthermore\, the merely complex cannot properly represent intrin
sic relativistic quantum properties such as the intrinsic spin. If one doe
s not have the proper theory\, the internal behaviour of the elementary pa
rticles\, their mutual inter-actions\, and the very quantum properties of
collective quantum systems\, such as high-temperature superconductors\, ca
nnot be properly thought about at all.\n\nThe new theory presented here a
ims to rectify those deficiencies: it treats the elementary particle masse
s in a fundamentally different way to Dirac\, incorporating them as a pair
of elements within a hypercomplex algebra including both the complex alge
bra\, and the quaternion algebra as sub-algebras. This allows a simpler\,
and even more beautiful equation than the Dirac or Maxwell equations to be
written down\, which yet contains them both. This equation may be written
simply as dG=C\, where "d" is a relativistic space-time derivative\, "G"
is a sixteen component multi-vector\, and "C" is a sixteen component array
of real constants\, most of which are zero.\n\nThe new theory opens up ne
w vistas\, new thinking\, and new connections. It provides an underlying b
asis to the theory of Quantum ElectroDynamics\, encompasses the Newton\, M
axwell and Einstein\, and removes all of the outstanding problems in RQM.\
n\nThe talk will focus on answering the list of questions posed by the gro
up (repeated below)\, as well as a set of further fundamental questions\,
including the origin of the g-2 term in the theory. This will include the
nature of the "generations" of particles in the standard model. It is argu
ed that the addition of this new element to the "standard model" will allo
w one to promote to a "standard theory" fit for progressing the new challe
nges of the 21st century.\n\nQuestions to be answered include\, but are no
t limited to:\n\nWhy electric charge is quantized.\nWhere the Coulomb inte
raction comes from\nHow one can prevent infinites e.g. of electric field o
f a point charge\nOrigins of the induced magnetic dipole and the intrinsic
angular momentum\nOrigin of the zitterbewegung/clock of the electron\nWhy
we have 3 generations of leptons\nWhy the proton is lighter than neutron\
nWhat holds nuclei together against the Coulomb force\nWhat holds charged
elementary particles together against the enormous Coulomb repulsion\nHow
to get gravity from relativistic quantum mechanics and Q.E.D.\n\nThe talk
will focus on answering the list of questions posed by the group\, includi
ng the nature and origin of charge\, the reason for and the nature of the
"generations" of particles in the standard model. It is argued that the ad
dition of this new element to the "standard model" will allow one to promo
te to a "standard theory" fit for progressing the new challenges of the 21
st century.\n

DESCRIPTION:Title: Extrinsic Quaternion Spin\nby Bryan Sanctuary (McGill Universit
y) as part of QM Foundations & Nature of Time seminar\n\n\nAbstract\nIf th
e symmetry of a spin ½ is changed from SU(2) to the quaternion group\, S8
\, then spin changes from a point particle to one with a 2D structure.
This reveals a missed property of spin. In addition to the usual up and do
wn polarized states that are measured\, two additional coherent states for
L and R helicity are found. This is not the usual helicity defined in pa
rticle physics\, but an additional attribute of spin. Under the quaternion
group\, symmetric polarizations are described by the Pauli spin vector\,
$\\sigma$ and the antisymmetric helicity by the bivector\, $i\\sigma$. Mo
reover\, surprisingly\, the four states of quaternion spin form one partic
le in the Dirac field which replaces the interpretation of Dirac whereby t
he two-dimensional Dirac spin and its mirror are treated as measured spin
and its antimatter twin.\n\nPolarization and coherence are two complementa
ry elements of reality\, analogous to position-momentum\; angular momentum
and angle\; and energy and time.\n\nMoreover\, it is found that the helic
ity accounts for the correlation found in coincident EPR experiments which
give an apparent violation of Bell’s Inequalities. As seen in the figu
re\, the simulation gives the correlation and more that is observed in exp
eriment. The simulation is trivial\, simply finding which way the spin ax
is spins. \n\nThe talk is pedagogical with simple geometric arguments to d
escribe a separated EPR pair with no entanglement. This obviates the need
for non-local connectivity between Alice and Bob and shows that the appar
ent violation of Bell’s Inequalities is evidence for local realism\, and
not non-locality.\n\nThe theory has no Local Hidden Variables\, so Bell
’s Theorem is irrelevant\, and always satisfied.\n

DESCRIPTION:Title: Particles as Maxwellian Solitons\nby Anton Vrba as part of QM F
oundations & Nature of Time seminar\n\n\nAbstract\nIn unstressed vacuum EM
traveling plane waves propagate on a linear path. Question: Can an electr
omagnetic wave travel on a closed and curved 3-dimensional path\, say a sp
herical-like path\, and how to formulate such a paths without using superp
ositioning? Furthermore\, the Maxwell equations are field (flux per area)
equations which begs the second question: Are there equivalent potential (
flux per distance) and flux equations to model EM-potential and EM-flux wa
ves? This presentation answers both questions in the affirmative from a pu
rely mathematical point of view. The new insight developed here could prov
ide a tool box to envision Maxwellian solitons\, a possible aid\, and supp
ortive view\, to further the understanding of particles.\n \nThe Maxwell e
quation and the derived d'Alembert wave equation cannot provide the answer
s to the above questions. We require a velocity vector in the Maxwell form
ulations. The talk presents the proof that the simultaneous vector crosspr
oduct equations\n{ E = u × B\; u = (B×E)/∥B∥^2\; B= ( E×u)/∥u∥^
2} --- (1)\nare a powerful reformulation of the Maxwell equations in vacuu
m\, if u \, B and E are functions of time only\, therefore (1) also descri
bes EM-waves in 1D (radio waves and photons)\, 2D and 3-dimensions (partic
les). The figure sketches a three dimensional wave\, here we note that E
is always radiant and B and u tangential.\n\nOn the premise that equation
set (1) also describes wave action (here electric action) it must follow t
hat a purely mathematical derivation for ϵ _0 and μ_0\, in terms of e an
d h\, should emerges from (1)\, indeed it is so and is demonstrated. Lever
aging (1) to describe flux-waves requires the equivalent expressions for
ϵ_f and μ_f\, and after deriving these the Planck energy equivalence E=
hf emerges from (1). The solutions to (1) set in flux are easily quantifia
ble\; for the 3D-wave the following are identifiable: up/down\, spin on tw
o axes\, charge polarity\, and path closure 2nπ\, with n an integer. Th
e proposed description for particles is congruent to the Bohm˗de Broglie
interpretation of quantum mechanics and a nonlocal hidden variable\; this
is discussed too.\n\nPapers: Maxwell and Solitons: https://neophysics.org/

rties\nby Vivian Robinson as part of QM Foundations & Nature of Time s
eminar\n\n\nAbstract\nThis presentation expands on the work of Williamson
and van der Mark [2]\, that electrons were photons of the appropriate ener
gy making two revolutions per wavelength. It uses only three space dimensi
ons and time\, as well as known physical properties and constants. It show
s how that structure gives all particles such properties as mass\, dimensi
ons\, the physical relationship between energy and mass given by E = mc2 a
nd the special relativity corrections with velocity. It introduces a fourt
h correction. It also shows the physical origins of charge\, magnetic mome
nt\, spin half-hbar\, spin superposition\, intrinsic spin hbar\, zitterbew
egung\, the particle’s de Broglie wavelength of particles\, and similar\
, as appropriate [3].\n\nThe structure of each of the individual particles
\, electrons\, protons\, neutrons\, neutrinos and some of the “elementar
y” particles is discussed. It shows how their structure gives them their
properties. Under this model\, multiple independent observations indicate
an electron neutrino’s rest mass is ≈ 10–4 eV/c2. Other apparently
peculiar neutrino properties are explained.\n\nThe value of a model of par
ticles includes how their structure and properties enable them to form the
larger particles in the world around us. The theory of nuclear binding un
der this model is presented. It shows how nucleons form into layers of a p
articular structure. Simple rules enable easy calculation of the structure
and some properties of any nucleus of any A and Z. Many nuclear structure
s are presented to show how it works. The match between theory and observa
tion is good across all atomic and mass numbers. It answers such questions
as the cause of the skin effect common to all nuclei\, why carbon nuclei
are equilateral triangular prism shaped\, why 208 Pb\, or 209 Bi\, are the
highest A and Z stable nuclei\, and more.\n\nA presentation is given of h
ow electrons form around nuclei. Their structure prevents them from spiral
ling into a nucleus. Their fixed\, or quantized\, energy levels are due to
the limited number of protons in a nucleus and each inner electron screen
ing out the charge of one proton. A discussion is given on how internal el
ectron properties give rise to electron pairing\, the foundation of chemic
al bonding.\n\nThe presentation shows the continuous relationship between
quantum mechanics and the structure of elementary particles\, with the spe
cial relativity corrections\, classical mechanics\, nuclear physics and ch
emistry. \n\n[1] V N E Robinson 2021 J. Phys. Commun. 5 035013 –

DESCRIPTION:Title: Quantum Mechanics from a Holographic Principle\nby Russell Thom
pson (University of Waterloo) as part of QM Foundations & Nature of Time s
eminar\n\n\nAbstract\nIn 1953\, Richard Feynman introduced a mathematical
trick through which quantum mechanical many-body problems could be solved
using classical statistical mechanics by treating the inverse of the therm
al energy in the partition function as an imaginary time dimension (a Wick
rotation). This opened the door for modern quantum simulation methods suc
h as path integral Monte Carlo\, centroid molecular dynamics and ring poly
mer molecular dynamics which are solved classically by using the extra\, f
ictitious\, dimension. Practitioners of this quantum-classical isomorphism
often refer to the quantum particles they are simulating as “ring polym
ers” since the imaginary time parameter describes a one-dimensional traj
ectory that starts and stops at the same position in space\, forming a clo
sed loop when projected into 3D. It has been shown that polymer self-consi
stent field theory (SCFT) also obeys the quantum-classical isomorphism\, a
nd is\, under the right conditions\, also equivalent to quantum density fu
nctional theory (DFT). Since the theorems of DFT guarantee equivalence bet
ween the predictions of DFT and those of of quantum mechanics\, the mathem
atics of SCFT in a 5D thermal-space-time must be dual to those of 4D non-r
elativistic quantum mechanics — a holographic principle. This requires s
peculating that Feynman’s thermal dimension is physically real instead o
f just a trick of the math. The 5D picture requires fewer postulates than
most descriptions of quantum mechanics and uses only classical concepts\,
albeit in a higher dimensional space. I will give an introductions to the
SCFT approach\, show some numerical solutions to the non-linear SCFT equat
ions\, and consider the prospects\, applications and significant limitatio
ns of the methodology.\n

ations & Nature of Time seminar\n\n\nAbstract\nLouis de Broglie in the beg
inning 20th century voices his theory of a double solution\, according to
which a pilot wave accompanies a particle\, simulated as a point singulari
ty\, along the most optimal path from its creation on a source up to the d
etection. The pilot wave is a real hidden wave\, which is similar to the w
ave function resulting from the solution of the Schrödinger equation. \nT
his theory is in agreement with de Broglie's postulate about the matter wa
ves.\nIn this article we mention the Helmholtz decomposition theorem accor
ding to which any velocity may be represented as a sum of two velocities -
- irrotational and solenoidal ones. The first velocity stems from the grad
ient of the scalar field. The second occurs from a pseudo-vector field. We
proclaim that the gradients of the scalar field define guiding paths of t
he pilot wave. While the pseudo-vector field defines a particle solenoidal
filling. \nWe give mathematical models of the irrotational and solenoidal
flows simulating the position of a particle in a guiding wave.\nModified
Navier-Stokes equation in pair with the continuity equation resulting in t
he Schrödinger equation gives such solutions consisting of superposition
of the irrotational and solenoidal flow\n

DESCRIPTION:Title: Quantum Mechanics: Strange Particle Theory or Classical Field Theor
y?\nby Sergey Rashkovskiy (RAS) as part of QM Foundations & Nature of
Time seminar\n\n\nAbstract\nIn the late 19th and early 20th century\, phys
icists came to the conclusion that phenomena such as (i) thermal radiation
\; (ii) photoelectric effect\; (iii) the Compton effect\; (iv) the structu
re of the atom and its stability\; (v) the discrete spectrum of spontaneou
s emission and the very nature of spontaneous emission\; (vi) anomalous Ze
eman effect\; (vii) the Stern-Gerlach effect and a number of other atomic
phenomena cannot be described within the framework of classical mechanics
and classical electrodynamics\, i.e. within the framework of a theory in w
hich the electron is considered a classical charged particle that obeys Ne
wton's laws of motion\, and its interaction with an electromagnetic field
is described by Maxwell's laws of classical electrodynamics. As a result o
f a relatively short search\, the main ideas were formulated that formed t
he basis of modern quantum theory: (a) electromagnetic radiation is quanti
zed\, both at the moment of radiation and when interacting with matter (at
oms)\; (b) an electron in an atom can only be in discrete states\, transit
ions between which (spontaneous or forced) are accompanied by the emission
or absorption of a quantum of electromagnetic radiation - a photon. The p
innacle of the development of quantum theory was the discovery of the Schr
ödinger equation and its extended forms - the Pauli\, Klein-Gordon and Di
rac equations. These equations have proven their predictive power in relat
ion to many so-called quantum phenomena. Thus\, on the one hand\, the elec
tron began to be described by a certain field - a wave function\, continuo
usly distributed in space and time\, satisfying the wave equations\, and o
n the other hand\, continued to be considered as a point charged particle.
As a result\, a number of paradoxes have arisen that have not found a fin
al explanation within the framework of orthodox quantum mechanics. I brief
ly analyze the well-known paradoxes of quantum mechanics and their interpr
etations and show that in order to explain the paradoxes that have arisen\
, the adherents of wave-particle duality were forced to introduce new hypo
thetical physical objects or hypothetical phenomena that led to the emerge
nce of new paradoxes. As a result\, the number of paradoxes in quantum mec
hanics has multiplied exponentially.\n\nAt present\, the point of view is
considered official\, according to which the above mentioned phenomena can
not be described within the framework of the concepts of classical physics
\, i.e. without energy quantization and without using the apparatus of qua
ntum electrodynamics.\n\nI show that we can avoid the QM-paradoxes if we c
onsider some classical wave field (“an electron wave”) instead of elec
tron as a particle and consider the wave equations (Dirac\, Klein-Gordon\,
Pauli and Schrödinger) as the field equations for an electron field simi
lar to Maxwell equations for the electromagnetic field.\n\nI show that suc
h an electron field has an electric charge\, an intrinsic angular momentum
(spin) and an intrinsic magnetic moment continuously distributed in the s
pace.\n\nIn the framework of classical electrodynamics\, we obtained the n
onlinear Schrödinger equation\, which accounts for the inverse action of
self-electromagnetic radiation of the electron wave. I show that this equa
tion completely and consistently describes all known properties of the hyd
rogen atom within the framework of classical field theory without any quan
tization and additional hypothesis: namely\, the stability of an atom\, th
e nature and regularities of the spontaneous emissions of an atom\, a ligh
t-atom interactions\, the photoelectric effect\, the Compton effect\, the
thermal radiation\, etc. In particular\, Planck’s law for the spectral e
nergy density of thermal radiation and the Einstein A-coefficient for spon
taneous emission are derived in the framework of classical field theory wi
thout using the concept of “photon”.\n\nI show that the conventional c
orpuscular-statistical interpretation of atomic phenomena is only a misint
erpretation of continuous deterministic processes.\n\nThese results show t
hat quantum mechanics must be considered to be not a theory of particles b
ut a classical field theory in the spirit of classical electrodynamics.\n\
nIn conclusion\, I show how Dirac equation can be coupled with Maxwell equ
ation in order to construct the self-consistent Maxwell-Dirac theory.\n

QM Foundations & Nature of Time seminar\n\n\nAbstract\nWhile one-way quan
tum computers (1WQC) use reversible\, unitary evolution\, they treat bound
ary conditions in asymmetric way: allowing to fix only the initial states
by state preparation. There will be discussed their 2WQC enhancement addin
g CPT analog of such state preparation to also fix some final states with
physical constraints – using CPT analogs as e.g. pull/push\, negative/po
sitive pressure (e.g. radiation)\, stimulated emission/absorption enforcin
g deexcitation/excitation. For hydrodynamics realizations it could be done
by just connecting such chip into a circuit with pump: both pushing into
with positive pressure\, and pulling from with negative pressure. Mathemat
ically hydrodynamics is governed by similar wavelike equation as electroma
gnetism\, hence I will focus on more practical photonic quantum computers\
, e.g. with (unidirectional) ring laser acting as pump for photons. If suc
cessful\, thanks to better control of information flow\, analogously to Sh

\nby Aleksander A. Lasek (UMD) as part of QM Foundations & Nature of T

mental observations of the internal thermalization of quantum many-body sy
stems. Often\, the global energy and particle number are conserved and the
system is prepared with a well-defined particle number—in a microcanoni
cal subspace. However\, quantum evolution can also conserve quantities\, o
r charges\, that fail to commute with each other. Noncommuting charges hav
e recently emerged as a subfield at the intersection of quantum thermodyna
mics and quantum information. I will give a brief introduction to the fie
ld of quantum noncommuting thermodynamics\, as well as present our origina
l results. Until recently\, this subfield has remained theoretical. We ini

DESCRIPTION:Title: Deriving Quantum Formalism from Information Limits in Microscopic S
ystems\nby Mehran Shaghaghi (UIC) as part of QM Foundations & Nature o
f Time seminar\n\n\nAbstract\nWhile the standard postulates of quantum mec
hanics successfully predict a wide range of phenomena\, their physical und
erpinnings remain elusive. In this presentation\, I derive the standard fo
rmalism of quantum theory—Born’s rule\, Hilbert space formalism\, and
Schrödinger equation—from the limitations of information accessibility
in microscopic systems. I demonstrate that information-theoretic constrain
ts imposed on microscopic systems with a single variable lead directly to
their inherent probabilistic behavior under different measurement scenario
s. This limitation\, combined with the conservation of probability\, is ut
ilized to derive Born's probability rule\, the Hilbert space formalism\, a
nd ultimately\, the Schrödinger equation governing the dynamics of these
systems. Furthermore\, I establish a connection between these single-varia
ble systems and traditional quantum systems. I show that coherence\, essen
tial for observing quantum phenomena\, restricts the number of independent
variables in a coherent beam to just one\, thereby supporting the connect
ion between our framework and established quantum phenomena. This work sug
gests that quantum phenomena may emerge from the fundamental limitations o
f information accessibility. It offers a new perspective on the foundation
s of quantum theory and opens new avenues for further exploration.\n

DESCRIPTION:Title: Geometric interpretation of the Standard Model as topological excit
ations\nby Jarek Duda (JU) as part of QM Foundations & Nature of Time
seminar\n\n\nAbstract\nIn perturbative QFT we decompose scenarios into Fey
nman ensemble of diagrams\, each of them should correspond to a field conf
iguration - I would like to present and discuss geometric/topological appr
oach to find them\, based on liquid crystal Landau-de Gennes model. To enf
orce charge quantization in Gauss law\, we interpret dual F tensor as curv
ature of a deeper field (Faber’s approach)\, this way Gauss law counts i
ts topological charge. To prevent infinite energy of singularity in its ce
nter\, we use Higgs-like potential to regularize it to a finite energy (ma
ss)\, what leads to short range corrections of Coulomb interaction\, in ag
reement with the running coupling effect (arXiv:2210.13374). Living in 3D\
, charges appear in 3 families of different mass\, resembling 3 leptons. T
here are also 3 types of vortices resembling color strings - which inward/
outward field rotation by pi would correspond to elementary electric (as t
opological) charge\, and fractional rotations to 6 types of quarks\, e.g.
appearing in quark-antiquark pairs with increased energy between them for
confinement. The u quark is preferred energetically due to suggested baryo
n configuration\, explaining why proton is lighter than neutron\, also e.g
. binding mechanism and electric quadrupole moment of deuteron. Hadronizat
ion can be viewed here through reconnections of such high energy color str
ing into various final configurations. Suggested neutrino oscillations thr
ough field rotations also seem in agreement: mainly between muon and tau n
eutrino\, with more freedom in PMNS than CKM mixing matrices.\n

DESCRIPTION:Title: A particle model based on direct interpretation of Compton scatteri
ng measurements and gamma spectroscopy\nby Andras Kovacs as part of QM
Foundations & Nature of Time seminar\n\n\nAbstract\nI present a particle
model that is based on a direct interpretation of Compton scattering measu
rements\, gamma spectroscopy\, and magnetic moment data. To correctly inte
rpret nuclear measurements\, we strictly adhere to foundational Physics la
ws\, such as the Maxwell and Klein-Nishina equations. It turns out that an
electron's and a proton's internal structures can be modeled analogously\
; the main difference is the topology of their Zitterbewegung. This result
implies that the neutron-proton difference is the additional presence of
a negative elementary charge\, i.e. the neutron has two sub-particles. We
develop a precise mass measurement method for measuring the negative charg
e's mass within the neutron\, and also survey relevant experiments. Numero
us experiments converge to the same result: the neutron comprises a proton
and a nuclear electron\, whose mass is 1.554 MeV\, and the binding energy
of these two neutron components is 0.26 MeV. Our work clarifies that all
tangible matter comprises three elementary particle types: electron\, nucl
ear electron\, and proton. We begin the discussion of unstable particles b
y considering magnetic moment difference between an electron and muon. Fin
ally\, we discuss what pion-related nuclear reactions reveal about the pio
n's internal structure. The reviewed experimental data lead to a reasonabl
e approximation of the muon's and pion's internal structures as well. The
muon turns out to be an elementary particle\, the neutral pion has two sub
-particles\, while the charge pion has three sub-particles.\n

DESCRIPTION:Title: Non-Abelian transport distinguishes three usually equivalent notion
s of entropy production\nby Billy Braasch (QuICS\, UMD) as part of QM
Foundations & Nature of Time seminar\n\n\nAbstract\nA fundamental challeng
e is to define quantum thermodynamic quantities—for example\, heat\, wor
k\, and entropy production. We extend the definition of entropy production
to a deeply quantum regime involving noncommuting observables [1]. Consid
er two systems prepared in different thermal states. A unitary transports
observables (“charges”) between the systems. Three common formulae mod
el the entropy produced. They cast entropy as an extensive thermodynamic v
ariable\, an information-theoretic uncertainty measure\, and a quantifier
of irreversibility. Often\, the charges are assumed to commute with each o
ther (e.g.\, energy and particle number)\, and the entropy-production form
ulae equal each other. Yet quantum charges can fail to commute\, inviting
generalizations of the three formulae. Charges’ noncommutation\, we find
\, breaks the formulae’s quivalence. Furthermore\, different formulae qu
antify different physical effects of charges’ noncommutation on entropy
production. This work opens the door of stochastic thermodynamics to charg
es that are peculiarly quantum by failing to commute with each other.\n

DESCRIPTION:Title: Potential new applications of laser causing deexcitation\, like emi
ssion coefficient mapping\, radiotherapy or 2WQC\nby Jarek Duda (Jagie
llonian University) as part of QM Foundations & Nature of Time seminar\n\n
\nAbstract\nWhile naively laser only excites target\, it can also cause it
s deexcitation – as stimulated emission\, backward ASE (amplified sponta
neous emission)\, or in Rabi cycle cyclically causing excitation and deexc
itation. STED microscopy is a popular application of laser causing deexcit
ation - I would like to propose and discuss a few more\, based on its prop
erties suggested by CPT symmetry. For example\, while CT scanner makes 3D
maps of absorption coefficient\, CPT symmetry suggests how to analogously
measure/map emission coefficients. Related medical applications could be c
ausing deexcitation of autoluminescent molecules like NADH\, e.g. to starv
e cancer tissue. Finally\, the original motivation was more symmetric and
powerful two-way quantum computers (2WQC)\, for example with photonic chip
between coupled laser resonators\n

DESCRIPTION:Title: Electron clock\, neutrino oscillation propulsion from energy minimi
zation by curvature coupling\nby Jarek Duda as part of QM Foundations
& Nature of Time seminar\n\n\nAbstract\nWhile it is relatively easy to obt
ain quantized electric charges as topological\, the difficult part is to u
nderstand why it has also non-quantized gravitational mass (local curvatur
e)\, and periodic process (like electron clock\, neutrino oscillation) alr
eady in the lowest energy state - formally making it a time crystal.\nSuch
mechanism automatically appeared (arXiv:2108.07896) by extending SO(3) va
cuum dynamics leading to EM+QM\, to SO(1\,3) adding boosts getting 2nd set
of Maxwell equations for gravitoelectromagnetism (GEM)\, and EM-GEM inter
action between them - due to spacetime signature\, getting negative Hamilt
onian terms preferring both local curvature for gravitational mass\, toget
her with nonzero time derivative - energetically preferred periodic proces
s.\nI will start with 1+1D toy model showing this mechanism on phi^4 kink
(arXiv:2501.04036)\, then introduce to the candidate of complete model.\n

Magnetic Flux\nby Dhiraj Sinha (Plaksha University) as part of QM Foun
dations & Nature of Time seminar\n\n\nAbstract\nCurrently\, the energy of
a photon is considered to be an experimental fact which does not have any
formal mathematical derivation and for over 100 years\, we have been told
that Maxwell's electromagnetism cannot explain how light energises electro
ns. The focus of the talk would be on looking at the role of Maxwell's e
quations in defining light matter interaction at optical frequencies. The
temporal variation of magnetic flux of electromagnetic radiation offers a
pathway towards derivation of the energy of a photon. The theoretical fra
mework offers a novel perspective on looking at the missing link between c
lassical electromagnetism and quantum mechanical concept of a photon.\n
