The Spectrum in the Sachdev-Ye-Kitaev Model

arXiv:1601.06768 · doi:10.1007/JHEP04(2016)001

Abstract

The SYK model consists of fermions in dimensions with a random, all-to-all quartic interaction. Recently, Kitaev has found that the SYK model is maximally chaotic and has proposed it as a model of holography. We solve the Schwinger-Dyson equation and compute the spectrum of two-particle states in SYK, finding both a continuous and discrete tower. The four-point function is expressed as a sum over the spectrum. The sum over the discrete tower is evaluated.
