Dissipative Quantum Battery from Many-Body Scars
Jinglin Liu, Yiming Liu, Mingdi Xu +1
We propose an autonomous quantum-battery protocol based on dissipatively selected quantum many-body scars. Using an embedding-type spin chain with an exact scar tower and a general…
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…
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 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…
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…
