A new universal ratio in Random Matrix Theory and chaotic to integrable transition in Type-I and Type-II hybrid Sachdev-Ye-Kitaev models

Fadi Sun, Yu Yi-Xiang, Jinwu Ye +1

We investigate chaotic to integrable transition in two types of hybrid SYK models which contain both $q=4$ SYK with interaction $J$ and $q=2$ SYK with an interaction $K$ in…
