Operator Size Distribution in Large N Quantum Mechanics of Majorana Fermions
read the original abstract
Under the Heisenberg evolution in chaotic quantum systems, initially simple operators evolve into complicated ones and ultimately cover the whole operator space. We study the growth of the operator ``size'' in this process, which is related to the out-of-time-order correlator (OTOC). We derive the full time evolution of the size distribution in large $N$ quantum mechanics of Majorana fermions. As examples, we apply the formalism to the Brownian SYK model (infinite temperature) and the large $q$ SYK model (finite temperature).

Higher-Order Corrections to Scrambling Dynamics in Brownian Spin SYK Models
Operator growth in Brownian spin SYK is solved beyond leading order with a generating-function 1/N perturbation theory; higher-order corrections set the late-time universal (two-body) and parity-protected (three-body)...
