DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EASW/9/">Ref
 lected entropy for an evaporating black hole</a>\nby Yang Zhou (Fudan Univ
 .) as part of East Asian String Webinars\n\n\nAbstract\nBlack hole informa
 tion paradox is a problem over 40 years. Recent progress shows hint toward
 s a new understanding of the black hole interior as part of the Hawking ra
 diation\, which they called island. In particular the island formula for t
 he Von Neumann entropy of Hawking radiation is consistent with unitarity. 
 In this talk I will discuss how to extract more information of the island 
 by computing the correlation in Hawking radiation. In particular we study 
 reflected entropy (as a correlation measure of mixed states) and propose a
  quantum extremal surface for reflected entropy. Based on that\, we find a
  formula for reflected entropy with island cross section as its area term 
 in gravitational system.\n
