Dear colleagues,

You are cordially invited to the online seminar of the Group for 
Gravitation, Particles and Fields, which will be held on Friday, 3 
December 2021 at 11:00 via the BigBlueButton platform (link is given 
below).


The talk entitled

Black hole entropy and the information loss paradox

is a continuation of the "Black hole entropy" series of seminars and 
will be given by Dragoljub Gocanin (Faculty of Physics, University of 
Belgrade).

Abstract: This talk will be devoted to the so-called wormhole replica 
trick and the notion of an island - a kind of a quantum extremal surface 
recently advocated by Maldacena. We will explain how the application of 
the holographic principle leads to the unitary Page curve. A 
generalization of the original formula for a generalized entropy is 
achieved via the notions of a quantum extremal surface and an island. 
Using the gravity path integral we will present additional arguments in 
favour of this approach.
