DESCRIPTION:Title: Holographic entanglement entropy for TTbar-deformed CFTs<
/a>\nby Luis Apolo (University of Amsterdam) as part of Integrability\, Du
ality and related topics\n\n\nAbstract\nTTbar-deformed CFTs with a negativ
e deformation parameter have been proposed to be dual to Einstein gravity
on AdS3 with a finite cutoff. In this talk\, I will present an extension o
f cutoff AdS3 holography that is valid for positive values of the deformat
ion parameter. In this case\, turning on the deformation parameter brings
the asymptotic boundary of AdS3 to a finite cutoff in an auxiliary AdS3 sp
acetime. I will show that the theory living at the cutoff surface reproduc
es many features of TTbar-deformed CFTs with a positive deformation parame
ter. Furthermore\, I will give a geometric prescription for computing the
holographic entanglement entropy of an interval at the cutoff surface. The
holographic entanglement entropy is finite and features a minimum length
scale\, as expected for TTbar-deformed CFTs.\n

DESCRIPTION:Title: Comments on Heavy Operators in N=4 SYM\nby Minkyoo Ki
m (Sogang University) as part of Integrability\, Duality and related topic
s\n\n\nAbstract\nFor N=4 SYM in the planar limit\, its spectrum is complet
ely solved at finite coupling through integrability. The dynamics of sin
gle-trace operators and worldsheet formulation of holographic dual strings
are such cases. On the other hand\, the spectrum of heavy operators\, w
hich is a holographic dual to giant graviton D-branes\, cannot be restrict
ed to the planar limit and therefore is not generally integrable. In thi
s talk\, I would like to introduce techniques that have been developed to
achieve analytic results in these situations. In particular\, I shall re
view some established ideas based on group representation theory and comme
nt on some new results.\n

DESCRIPTION:Title: Topological gauging and non-relevant deformations of Quan
tum Field Theories\nby Stefano Negro (New York University) as part of
Integrability\, Duality and related topics\n\n\nAbstract\nIn the last few
years\, much attention has been devoted to the study of a peculiar class o
f irrelevant deformations of 2-dimensional Quantum Field Theories\, known
as “Solvable Irrelevant Deformations”. The poster child of these is th
e celebrated “TTbar deformation”. They display unusual properties in t
he UV\, which can be described exactly\, their irrelevant nature notwithst
anding. For this reason they represent a sensible extension of Quantum Fie
ld Theory beyond the Wilsonian paradigm and have attracted a considerable
attention from the high energy theory community. The property of being sol
vable is shared with a wider class of deformations\, constructed out of pa
irs of conserved currents. In general these are marginal deformations\, th
us presenting very different UV properties. Nonetheless their structures a
re similar to the TTbar ones\, hinting at the existence of a universal des
cription.\n\nIn this talk I will present a very general framework that acc
ommodates both solvable irrelevant and solvable marginal deformations\, wh
ich amounts to a “topological gauging” of the symmetries of the system
. Through simple path integral computations\, I will recover the main feat
ures of these theories and show their equivalence to TST and Yang-Baxter d
eformations. For the case of TTbar\, the topological gauging perspective e
xplains the previously not understood relation to field theory in non-comm
utative Minkowski space-time and to the centrally extended Poincaré algeb
ra.\n

DESCRIPTION:Title: Integrability from Disorder in Quantum Many-Body Systems
\nby John. Z. Imbrie (University of Virginia) as part of Integrability
\, Duality and related topics\n\n\nAbstract\nA quantum system is said to b
e many-body localized (MBL) if one can find a complete set of local integr
als of motion (LIOMs). This leads to a breakdown of thermalization. I will
summarize a proof that certain one-dimensional spin chains have an MBL ph
ase (the proof depends on a certain assumption on level statistics). In re
cent work with Morningstar and Huse\, we develop specific RG flow equation
s to study the critical phenomenon at the edge of the MBL phase. This tur
ns out to be similar to the Kosterlitz-Thouless (KT) flow\, but there are
important differences that place the MBL transition in a new universality
class.\n

DESCRIPTION:Title: Boundary and plane defect criticality in the 3d O(N) mod
el\nby Max A. Metlitski (MIT) as part of Integrability\, Duality and r
elated topics\n\n\nAbstract\nIt is known that the classical O(N) model in
dimension d > 3 at its bulk critical point admits three boundary universal
ity classes: the ordinary\, the extraordinary and the special. The extraor
dinary fixed point corresponds to the bulk transition occurring in the pre
sence of an ordered boundary\, while the special fixed point corresponds t
o a boundary phase transition between the ordinary and the extra-ordinary
classes. While the ordinary fixed point survives in d = 3\, it is less cle
ar what happens to the extraordinary and special fixed points when d = 3 a
nd N is greater or equal to 2. I'll show that formally treating N as a con
tinuous parameter\, there exists a critical value Nc > 2 separating two di
stinct regimes. For N < Nc the extra-ordinary fixed point survives in d =
3\, albeit in a modified form: the long-range boundary order is lost\, ins
tead\, the order parameter correlation function decays as a power of log r
. For N > Nc there is no fixed point with order parameter correlations de
caying slower than power law. I'll discuss how these findings compare to r
ecent Monte-Carlo studies of classical and quantum spin models with SO(3)
symmetry.\n

DESCRIPTION:Title: Line Operators in Chern-Simons-Matter Theories and Boson
ization in Three Dimensions\nby Deliang Zhong (Tel Aviv University) as
part of Integrability\, Duality and related topics\n\n\nAbstract\nWe stud
y Chern-Simons theories at large N with either bosonic or fermionic matter
in the fundamental representation. The most fundamental operators in thes
e theories are mesonic line operators\, the simplest example being Wilson
lines ending on fundamentals. We classify the conformal line operators alo
ng an arbitrary smooth path as well as the spectrum of conformal dimension
s and transverse spins of their boundary operators at finite 't Hooft coup
ling. These line operators are shown to satisfy first-order chiral evoluti
on equations\, in which a smooth variation of the path is given by a facto
rized product of two line operators. We argue that this equation\, togethe
r with the spectrum of boundary operators\, are sufficient to uniquely det
ermine the expectation values of these operators. We demonstrate this by b
ootstrapping the two-point function of the displacement operator on a stra
ight line. We show that the line operators in the theory of bosons and the
theory of fermions satisfy the same evolution equation and have the same
spectrum of boundary operators.\n

DESCRIPTION:Title: On the classification of UV completions of integrable
$T \\bar{T}$ deformations of CFT\nby Andre LeClair (Cornell Universit
y) as part of Integrability\, Duality and related topics\n\n\nAbstract\nIt
is well understood that 2d conformal field theory (CFT) perturbed by an i
rrelevant $T\\bar{T}$ perturbation of dimension $4$ has universal propert
ies. \nIn particular\, for the most interesting cases\, the theory dev
elops a singularity in the ultra-violet (UV)\, signifying a shortest pos
sible distance\, with a Hagedorn transition in applications to string th
eory. \nWe show that by adding an infinite number of higher $T\\bar{T}
_{s>1}$ irrelevant operators of positive integer scaling dimension $2(s+1
)$ with tuned couplings\, this singularity can be resolved and the theor
y becomes UV complete with a Virasoro central charge $c_{UV }> c_{IR}$ con
sistent with the c-theorem. \nWe propose an approach to classifying the
possible UV completions of a given CFT perturbed by $T\\bar{T}_s$ that are
integrable. \nThe main tool utilized is the thermodynamic Bethe ansatz.
\nWe study this classification for theories with scalar (diagonal) facto
rizable S-matrices. For the Ising model with \n$c_{IR} = \\tfrac{1}{2}$ w
e find 3 UV completions based on a single massless Majorana fermion descri
ption with \n$c_{UV} = \\tfrac{7}{10}$ and $ \\tfrac{3}{2}$\, which both
have $N=1$ SUSY and were previously known\, and we argue that these are
the only solutions to our classification problem based on this spectrum of
particles. We find \n 3 additional ones with a spectrum of 8 massless
particles related to the Lie group $E_8$ appropriate to a magnetic pertur
bation\nwith $c_{UV} = \\tfrac{21}{22} \, \\tfrac{15}{2}$ and $\\tfrac{31}
{2}$. We argue that it is likely there are more cases for this $E_8$ sp
ectrum. \nWe also study simpler cases based on $\\suthree$ and $\\sufour$
where we can propose complete classifications. For $\\suthree$ the inf
ra-red (IR) theory is the 3-state Potts model with $c_{IR} = \\tfrac{4}{5}
$ and we find 3 completions with $\\tfrac{4}{5} < c_{UV} \\leq \\tfrac{16
}{5}$. For the $\\sufour$ case\, which has $3$ particles and $c_{IR
} =1$\, and we find $11$ UV completions\nwith $1 < \\cUV \\leq 5$\, mo
st of which were previously unknown. (Based on work with Changrim A

DESCRIPTION:Title: Near BPS black holes and microstates in supergravity
\nby Matthew Heydeman (IAS) as part of Integrability\, Duality and related
topics\n\n\nAbstract\nIt is an open problem to understand the ultimate fa
te of the path integral in gravity and quantum black hole thermodynamics.
Recent progress has focused on supersymmetric black holes in asymptoticall
y AdS spacetimes in which the sum over classical BPS solutions reproduces
the superconformal index of the dual CFT. In a parallel line of developmen
t\, it has been understood that certain models of 2d gravity describe the
near horizon region of a near-extremal black hole. At strong coupling the
integral over metrics in these models may be done exactly\, and the soluti
on reveals a coarse-grained chaotic spectrum with no sharply defined micro
states. In this talk\, we will show that these two approaches are compat
ible and compute the low-temperature partition function of near-BPS black
holes via a gravitational path integral. Our approach uses an effective fi
eld theory of the near horizon geometry which reduces to an exactly solvab
le supersymmetric extension of the Schwarzian theory found in toy models o
f 2d gravity. The quantization of this theory gives a quantum gravitationa
l derivation of the extremal entropy and the superconformal index\, showin
g that supergravity at strong coupling may exhibit both exact integrable m
icrostates as well as a chaotic spectrum of near-BPS states. This approach
gives universal predictions which apply to both AdS and flat space black
holes as well as dual superconformal field theories such as N=4 SYM.\n

DESCRIPTION:Title: Sailing Past the Edge and Discovering the Island\nby
Tarek Anous (University of Amsterdam) as part of Integrability\, Duality
and related topics\n\n\nAbstract\nQuantum extremal surfaces and islands ha
ve led us to rethink the very meaning of microscopic entropy in the presen
ce of dynamical gravity. I will present some work elucidating how the isla
nd/QES prescription emerges in a simple doubly holographic setup where we
have analytic control. We will consider two holographic 2d CFTs joined at
an interface such that the bulk dual is a geometry that interpolates betw
een two locally 3d AdS geometries with different AdS lengths. In particula
r we will consider systems where the transition region is a thin brane wit
h tension T. In the limit of large tension\, the brane gets pushed outward
towards the boundary\, meaning the effective theory on the brane is confo
rmal and gravity almost decouples. We show precisely how the canonical CFT
entropy and the remaining gravity dynamics leads to an island formula in
this setup. The location of the island is identified with where the RT sur
face crosses the brane in the full holographic 3d picture.\n
