Strong Quantum Mpemba Effect from Exact Slow-Mode Selection in Constrained Rydberg Chains
Mingdi Xu, Kaixiang Lu, Xiang-Ping Jiang +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…
Observation of Switchable Chiral Magnons in an Altermagnet
Zheyuan Liu, Hodaka Kikuchi, Zijun Wei +8
Chiral magnons, the quanta of handed spin waves, transport spin angular momentum without energy loss due to Joule heating. The recently discovered altermagnets were proposed to hos…
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…
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…
