Abstract

Generalizing previous results for N=0N=0 and N=1N=1, we analyze N=2N=2 JT supergravity on asymptotically AdS2{}_2 spaces with arbitrary topology and show that this theory of gravity is dual, in a holographic sense, to a certain random matrix ensemble in which supermultiplets of different RR-charge are statistically independent and each is described by its own N=2N=2 random matrix ensemble. We also analyze the case with a time-reversal symmetry, either commuting or anticommuting with the RR-charge. In order to compare supergravity to random matrix theory, we develop an N=2N=2 analog of the recursion relations for Weil-Petersson volumes originally discovered by Mirzakhani in the bosonic case.
