 D black hole sigma models from an integrable spin chain</a>\nby Gleb Kotou
 sov (Leibniz University Hannover) as part of NHETC Seminar\n\n\nAbstract\n
 The staggered six-vertex model is a 1D critical integrable spin chain that
  exhibits a variety of interesting universal behaviour. This includes a re
 gime where the spectrum of critical exponents contains a continuous compon
 ent and matches that of the Euclidean version of the 2D black hole non-lin
 ear sigma model. In this talk the relation between the scaling limit of th
 e vertex model and the Euclidean/Lorentzian black hole sigma models is dis
 cussed. Some new results on the density of states of the continuous spectr
 um for the Euclidean black hole CFT are presented\, which were obtained vi
 a an analysis of the lattice system. The talk is largely based on the work
  2010.10603.\n
