Title: Large q expansion in the Sachdev-Ye-Kitaev model

Abstract

We consider the Sachdev-Ye-Kitaev (SYK) model, where interaction involves q fermions at a time. We find the 1/q2 correction to the thermal two-point function in the large q expansion. Using this result, we find the 1/q3 correction to the SYK free energy.
