Description
We will give an overview of recent developments in two dimensional Jackiw-Teitelboim (JT) gravity in asymptotically AdS, and applications. The talk will be separated into two parts. First we will review perturbative quantum effects in JT gravity, which are a good approximation of low energy physics for a variety of systems including near-extremal black holes in higher dimensions and SYK-like models. These effects become large at small enough temperatures modifying the spectrum and correlators. Still, they are not enough to capture the unitarity of the black hole spectrum. In the second part of the talk, focusing on pure gravity, we will review non-perturbative effects originating from spacetime wormholes and sum over topologies. This leads to a concrete duality between a large class of two dimensional dilaton-gravity theories in asymptotically AdS and a disorder average over boundary Hamiltonians, described by random matrix theory.
