СЕМИНАР: Драгољуб Гочанин

У оквиру семинара Групе за гравитацију, честице и поља Института за физику у Београду, у петак, 3. децембра 2021. године у 11 часова путем BigBlueButton платформе, Драгољуб Гочанин (Физички факултет у Београду), одржаће предавање:

Black hole entropy and the information loss paradox

САЖЕТАК:

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.
