Today's #arXivsummary: https://arxiv.org/abs/2302.08876 by Shankar et. al. Authors consider the four-point function of a SYK-type model numerically and find that the Lyapunov exponent is maximal for a range of ratios of A and B-type Majorana fermions centered around equal population at strong coupling. #CondMat #StrEl #arXiv_2302_08876
