Quantum Mpemba effect in parity-time symmetric systems
Wanchen Ma, Junjie Liu
The quantum Mpemba effect (QMPE), an anomalous relaxation phenomenon, has been demonstrated in both closed and open Hermitian quantum systems. While some studies have linked the QM…

Dynamical non-Hermitian systems: Fingerprints and pure dephasing induced protection effect
Wanchen Ma, Hao Zhang, Junjie Liu
Non-Hermitian systems have shown promising potential for realizing quantum information tasks that lack counterparts in the Hermitian realm. Understanding the dynamical characterist…
