DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IAMP_seminar
 s/104/">A slightly different look at the bulk-edge correspondence in quant
 um Hall systems</a>\nby Stefan Teufel (University of Tübingen) as part of
  One world IAMP mathematical physics seminar\n\n\nAbstract\nThe bulk-edge 
 correspondence of transport coefficients in quantum Hall systems is usuall
 y shown for systems with a (mobility) gap in the bulk and at zero temperat
 ure. I will present recent results showing equality of magnetization in th
 e bulk and edge current in microscopic models without and with interaction
  between electrons. This equality holds at positive temperature and withou
 t assuming a (mobility) gap in the bulk\, and is robust to perturbations n
 ear the edges. I then discuss how the equality of transport coefficients c
 an be recovered from this form of bulk-edge correspondence\, at least in s
 ome cases. My talk is based on joint work with Horia Cornean\, Jonas Lampa
 rt\, Massimo Moscolari\, and Tom Wessel.\n
