报告摘要

JT gravity and SYK model provide a concrete model for NAdS2/CFT1 holography. Recently, the topology change in this gravitational path integral was found to be crucial for understanding some non-perturbative aspects in this holography, which is an intrinsic quantum signature. Connected manifold, like wormhole connecting two asymptotic boundary, and even higher genus surface, was shown to be important for blackhole information paradox, late time behavior of observables and level discreteness of boundary system. In this talk, I will briefly review these new developments, and talk about two aspect my collaborators and I worked on. (1) Factorization puzzle and half-wormhole conjecture. This involves the ensemble average in this low dimension holography and a possible scheme for non-averaged systems. (2)Explanation of subleading Weingarten coefficients in random unitary behavior of gravity and Brownian SYK. Both quantum chaos and topologically non-trivial solution plays and important role.
