DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PUHET/14/">T
 he OPE Randomness Hypothesis and Euclidean Wormholes</a>\nby Alex Belin (C
 ERN) as part of Princeton HET seminar\n\n\nAbstract\nRecent developments i
 n holography indicate that the semi-classical Euclidean path-integral of E
 instein gravity is much more powerful than previously anticipated. It is c
 apable of reproducing a unitary Page curve for black hole evaporation\, an
 d can even capture some features of the discrete nature of black hole micr
 ostates. Wormhole geometries play a key role in this context. I will propo
 se a mechanism to explain this in the CFT: the OPE Randomness Hypothesis. 
 This ansatz is a generalization of the Eigenstate Thermalization Hypothesi
 s which applies to chaotic CFTs\, and treats OPE coefficients of heavy ope
 rators as random variables with a given probability distribution. I will p
 resent two applications of this framework: First\, it resolves a factoriza
 tion puzzle in AdS_3/CFT_2 due to the genus-2 wormhole\, as raised by Maoz
  and Maldacena. Second\, it provides an argument against global symmetries
  in quantum gravity.\n
