Initial-state-dependent dephasing effect in non-Hermitian Su-Schrieffer-Heeger models
Tao Min, Junjie Liu
Understanding the dynamical evolution of non-Hermitian systems under extra external dissipation is essential. Dephasing, a major realistic dissipation, is conventionally considered…
Direct temperature readout in nonequilibrium quantum thermometry
Yan Xie, Junjie Liu
Quantum thermometry aims to measure temperature in nanoscale quantum systems, paralleling classical thermometry. However, temperature is not a quantum observable, and most theoreti…
Quantum Interaction Between Free Electrons and Light Involving First-order and Second-order Process
Hongteng Lin, Xiaotong Xiong, Junjie Liu +2
Photon-induced Near-field Electron Microscopy (PINEM) effect has revealed the quantum interaction between free electrons and optical near filed, which demonstrated plenty of novel…
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…
