Probing microstates of near-extremal black holes using n-point correlators in Jackiw-Teitelboim gravity and supersymmetric theories.

Abstract

The goal of this paper is to study two-point functions of chiral operators as a tool to learn about the microscopic properties of near-extremal black holes. We are in particular interested in what happens with the correlator at very large times since this can inform us about how much information about what interacted with the black hole is accessible to an outside observer. By first relating our system to a theory on the boundary, the limit we consider in detail is taking large times along the boundary. We are interested in this discussion because it can be used to study the ground states of near extremal black holes. We will demonstrate that these give the leading contribution to the late-time behavior of the two-point function.
