DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/11/">De
 nsity matrix for the 2D black hole from an integrable spin chain</a>\nby S
 ergei Lukyanov as part of London Integrability Journal Club\n\n\nAbstract\
 nTwenty years ago Maldacena\, Ooguri and Son constructed a modular invaria
 nt partition function for the Euclidean black hole (cigar)  NLSM. They als
 o proposed an expression for the corresponding density matrix.\nThis resul
 t played a key role in the formulation of the remarkable conjecture by Ikh
 lef\, Jacobsen and Saleur that the Euclidean black hole NLSM underlies the
  critical behaviour of a certain integrable spin chain.\nIn this talk we c
 ritically reexamine the above proposals.\n\nThe talk is based on the recen
 t (unpublished) joint work with\nV. Bazhanov and G. Kotousov.\n
