Critical JT Gravity
Alicia Castro,

In this talk, I will present JT-like gravity, a model of two-dimensional quantum gravity on constant negatively curved spacetimes, as a model of random hyperbolic surfaces. By studying the generating function of volumes of random hyperbolic surfaces with defects, i.e. weighted geodesic boundaries, we explore critical regimes where the surfaces develop macroscopic holes. We analyse the impact of this critical behavior on the density of states of the theory at the boundary, and we present a family of models that interpolate between systems with √E and E3/2, which are commonly found in models of JT Gravity coupled to dynamical end-of-the-world and FZZT branes.
