On free energy for deformed JT gravity

School
PHYSICS

Abstract:

In this talk, we will study a particular deformation of the Jackiw-Teitelboim gravity recently considered by Witten and others. We will compute the partition function of this model as well as its higher order correlators to all orders in genus expansion in the low temperature limit for small perturbations. In this limit, the results match with those obtained from the Airy limit of a Hermitian random matrix ensemble. Using this result, we will also study the free energy of the model. One observes that although the annealed free energy has pathological behaviors, under certain assumptions, the quenched free energy evalu ...
