Exact Quench Dynamics from Thermal Pure Quantum States
Hui-Huang Chen
We present an exact solution for entanglement entropy for the real-time dynamics following a quench from a thermal pure quantum (TPQ) state in a free-fermion system. In contrast to…

Symmetry resolved entanglement entropy after an inhomogeneous quench
Hui-Huang Chen, Xin-Liang Zhou, Jiayu Yin +1
We investigate the non-equilibrium time evolution of symmetry-resolved entanglement entropy (SREE) following an inhomogeneous quench in a critical one-dimensional free fermion syst…
