Exact moments of the Sachdev-Ye-Kitaev model up to order 1/N 2

Exact moments of the Sachdev-Ye-Kitaev model up to order 1/N 2

Abstract We analytically evaluate the moments of the spectral density of the q-body Sachdev-Ye-Kitaev (SYK) model, and obtain order 1/N 2 corrections for all moments, where N is the total number of Majorana fermions. To order 1/N, moments are given by those of the weight function of the Q-Hermite po...
