Abstract
We study correlation functions in the complex fermion SYK
model. We focus, specifically, on the h=2 mode which explicitly
breaks conformal invariance and exhibits the chaotic behaviour. We
numerically explore a fermion six-point OTOC, with two and three real-time folds, respectively. While our approach is expected to yield an early-time chaotic growth, we nevertheless observe a near-maximal value.
Following the program of Gross-Rosenhaus, we estimate the triple
short time limit of the six point function. Unlike the conformal
modes with high values of h, the h=2 mode has contact
interaction dominating over the planar in the large q limit.
