报告摘要：

In this talk, we will show how to match the thermodynamics of the (0 + 1)-dimensional SYK model, with that of a (1 + 1)-dimensional gravitational model. We focus on a model of deformed JT gravity, characterized by some unknown dilaton potential function and unknown dilaton-to-Maxwell field coupling. By finding the general solutions, we are able to find the Lagrangian which produces the same partition function and equation of state as that of the considered SYK model. We will show how to match the pole skipping points in 2D gravity and that of complex SYK.
