Sachdev-Ye-Kitaev models with complex fermions

ORAL

Abstract

We studied Sachdev-Ye-Kitaev models with complex fermions. We diagonalized the kernel matrix at finite chemical potential, and found the reparameterization and phase modes in the conformal limit. From the kernel, we read off the spectrum of operators that appear in the OPE expansion of two fermions. And from the UV correction in the two point function, we analyzed the kernel correction that leads to the effective action, and relates to the chaos behavior.
