Non-unitary dynamics of Sachdev-Ye-Kitaev chain
Chunxiao Liu, Pengfei Zhang, Xiao Chen
We construct a series of one-dimensional non-unitary dynamics consisting of both unitary and imaginary evolutions based on the Sachdev-Ye-Kitaev model. Starting from a short-range…

Subsystem Rényi Entropy of Thermal Ensembles for SYK-like models
Pengfei Zhang, Chunxiao Liu, Xiao Chen
The Sachdev-Ye-Kitaev model is an -modes fermionic model with infinite range random interactions. In this work, we study the thermal Rényi entropy for a subsystem of the SYK mod…
