DESCRIPTION:Speakers: Anna Hill Romero (IFIC (CSIC-UV))\nWe determine the 
 expression for the entanglement entropy at finite temperature for disk reg
 ions in conformal field theories that are dual to black holes in Einstein 
 gravity and Gauss-Bonnet gravity\, in the context of the AdS/CFT correspon
 dence. We use the Ryu-Takayanagi formula and its generalization for higher
 -curvature gravities\, respectively. We compute the low temperature expans
 ion of the holographic entanglement entropy relative to the vacuum state\,
  up to second order. The results are expressed in terms of the thermal ent
 ropy charge and the central charge in the correlator of two stress-energy 
 tensors\, applying the AdS/CFT dictionary. In Einstein gravity\, the expan
 sion coefficients are fixed. In Gauss-Bonnet gravity\, the first order coe
 fficient adopts a simple form in terms the thermal entropy charge\, sugges
 ting a possible universal character for this coefficient.\n\nhttps://indic
