Higher-Order Corrections to Scrambling Dynamics in Brownian Spin SYK Models
Tingfei Li, Miao Wang, Jianghui Yu
We investigate operator growth in a Brownian spin Sachdev--Ye--Kitaev (SYK) model with random all-to-all interactions, focusing on the full operator-size distribution. For Hamilton…

Graph-Theoretic Analysis of -Replica Time Evolution in the Brownian Gaussian Unitary Ensemble
Tingfei Li, Jianghui Yu
In this paper, we investigate the -replica time evolution operator for the Brownian Gaussian Unitary Ensemble (BGUE) using a graph-t…
