Non-Hermitian Linear Response Theory
Lei Pan, Xin Chen, Yu Chen +1
Linear response theory lies at the heart of quantum many-body physics because it builds up connections between the dynamical response to an external probe and correlation functions…

Linking invariant for the quench dynamics of a two-dimensional two-band Chern insulator
Xin Chen, Ce Wang, Jinlong Yu
We discuss the topological invariant in the (2+1)-dimensional quench dynamics of a two-dimensional two-band Chern insulator starting from a topological initial state (i.e., with a…

Competition between Chaotic and Non-Chaotic Phases in a Quadratically Coupled Sachdev-Ye-Kitaev Model
Xin Chen, Ruihua Fan, Yiming Chen +2
The Sachdev-Ye-Kitaev (SYK) model is a concrete solvable model to study non-Fermi liquid properties, holographic duality and maximally chaotic behavior. In this work, we consider a…
