 /">Bulk-Edge dualities in Topological Matter</a>\nby Manuel Asorey (Univer
 sity of Zaragoza) as part of Quantum Matter meets Maths (IST\, Lisbon)\n\n
 \nAbstract\nNovel bulk-edge dualities have recently emerged in topological
  materials from the observation of some phenomenological correspondences. 
 The similarity of these dualities with string theory dualities is very app
 ealing and has boosted a quite significant number of cross field studies.\
 nWe analyze the bulk-edge dualities in the integer quantum Hall effect\, w
 here due to the simpler nature of planar systems the duality can be analyz
 ed by powerful analytic techniques. The results show that the corresponden
 ce is less robust than expected. In particular\, it is highly dependent of
  the type of boundary conditions of the topological material. We introduce
  a formal proof of the equivalence of bulk and edge approaches to the quan
 tization of Hall conductivity for metallic plates with local boundary cond
 itions. However\, the proof does not work for non-local boundary condition
 s\, like the Atiyah-Patodi-Singer boundary conditions\, due to the appeara
 nce of gaps between the bulk and edge states.\n
