Non-Hermitian quantum phase transitions in the XY model induced by staggered imaginary Dzyaloshinskii--Moriya interaction
Hong Jiang, Xiang-Ping Jiang, Yan-Chao Li
We investigate non-Hermitian quantum phase transitions driven by staggered imaginary Dzyaloshinskii--Moriya (DM) interactions in a transverse-field chain. By virtue of a stagg…
Quantum phase transitions and quantum-information characterization of a non-Hermitian XY chain with staggered Dzyaloshinskii--Moriya interactions
Hong Jiang, Xiang-Ping Jiang, Yan-Chao Li
We investigate the phase diagram of a non-Hermitian XY chain with staggered Dzyaloshinskii--Moriya (DM) interactions using quantum-information methods. Through an alternating local…
Dissipation-tunable extended and localized steady states in a non-disordered lattice
Ming-Jie Tao, Yi-Ting Wang, Jing Li +3
Dissipation is usually regarded as a source of decoherence that suppresses quantum interference and localization. Here we show that suitably engineered dissipation can instead be u…
Dephasing-induced distinct mobility edges in a dimerized off-diagonal quasicrystal
Ming-Jie Tao, Yi-Ting Wang, Jing Li +3
Anderson localization and the mobility edge (ME) have been extensively studied in isolated aperiodic systems. Conventional theory suggests that dephasing and decoherence should dis…
Strong Quantum Mpemba Effect from Exact Slow-Mode Selection in Constrained Rydberg Chains
Mingdi Xu, Kaixiang Lu, Zijun Wei +3
CStrong quantum Mpemba acceleration requires suppressing the slowest visible Liouvillian relaxation channel, but a robust many-body mechanism for enforcing such suppression remains…
Symmetry-Induced Relaxation Comb and Strong Quantum Mpemba Effect in Long-Range XXZ Spin Chains
Zijun Wei, Mingdi Xu, Yefeng Song +3
We uncover a symmetry-filtered mechanism for anomalous dissipative relaxation in a long-range XXZ spin chain subject to local dephasing. At the isotropic point, the coherent Hamilt…
Critical Entanglement Dynamics at Dynamical Quantum Phase Transitions
Kaiyuan Cao, Mingzhi Li, Xiang-Ping Jiang +2
We investigate the critical behavior of momentum-space entanglement entropy at dynamical quantum phase transitions (DQPTs) in translationally invariant two-band insulators and supe…
Dissipative charging of tight-binding quantum batteries
Mingdi Xu, Yiming Liu, Yefeng Song +2
We investigate autonomous dissipative charging mechanisms for lattice quantum batteries within the framework of open quantum systems. Focusing on engineered Markovian dissipation,…
Quantum Pontus--Mpemba Effect in Dissipative Quasiperiodic Chains
Yefeng Song, Junxiao Chen, Xiangyu Yang +3
We investigate how quasiperiodic spatial structure enables protocol-induced acceleration in open quantum systems by analyzing the Pontus-Mpemba effect in one-dimensional chains sub…
Quantum Mpemba Effect in Dissipative Spin Chains at Criticality
Zijun Wei, Mingdi Xu, Xiang-Ping Jiang +2
The Quantum Mpemba Effect (QME) is the quantum counterpart of the classical Mpemba effect--a counterintuitive phenomenon in which a system initially at a higher temperature relax t…
Dissipation-Enhanced Localization in a Disorder-Free Lattice Gauge System
Xuanpu Yang, Xiang-Ping Jiang, Lei Pan
The lattice gauge model, as the simplest realization of a lattice gauge theory, exhibits rich and unconventional physics. One of its most remarkable features is diso…
Expedited thermalization dynamics in incommensurate systems
Mingdi Xu, Zijun Wei, Xiang-Ping Jiang +1
We study the thermalization dynamics of a quantum system embedded in an incommensurate potential and coupled to a Markovian thermal reservoir. The dephasing induced by the bath dri…
Dissipation induced localization-delocalization transition in a flat band
Mingdi Xu, Zijun Wei, Xiang-Ping Jiang +1
The interplay between dissipation and localization in quantum systems has garnered significant attention due to its potential to manipulate transport properties and induce phase tr…
Robustness of quantum many-body scars in the presence of Markovian bath
Xiang-Ping Jiang, Mingdi Xu, Xuanpu Yang +3
A generic closed quantum many-body system will inevitably tend to thermalization, whose local information encoded in the initial state eventually scrambles into the full space, kno…
