Critical JT gravity

A bstract In this paper, we investigate a critical behavior of JT gravity, model two-dimensional quantum gravity on constant negatively curved spacetimes. Our approach involves using techniques from random maps to the generating function Weil-Petersson volumes, which count hyperbolic surfaces with defects. The defects are weighted geodesic boundaries, and criticality is reached by tuning weights regime where macroscopic holes emerge in surface, namely non-generic . We analyze impact some universal features, such as its density states. present family models that interpolates between systems ρ 0 ( E ) ~ $$ \sqrt{E-{E}_0} E − 0 − 3 / 2 , commonly found coupled dynamical end-of-the-world FZZT branes, give precise definition what phase transition means geometry point view.
