Fate of dynamical quantum phase transitions from sudden quench to slow quench limit
Xiang Zhang, Fuxiang Li
Previous investigations of dynamical quantum phase transition (DQPT) have predominantly focused on sudden quench protocols. In this work, we systematically explore the fate of DQPT…
Fractional topology and multi-period re-quantization in open quantum systems
Xi Wu, Xiang Zhang, Fuxiang Li
We study fractional topological numbers in open quantum systems described by the Gorin--Kossakowski--Sudarsha--Lindblad master equation. Under symmetry conditions ensuring quantiza…
Anomalous Dynamical Scaling at Topological Quantum Criticality
Menghua Deng, Sheng Yang, Chen Sun +2
We study the nonequilibrium driven dynamics at topologically nontrivial quantum critical points (QCPs), and find that topological edge modes at criticality give rise to anomalous d…
Non-commutative Dynamic Approaches to the Kibble-Zurek Scaling Limit with an Initial Gapless Order
Zhe Wang, Chengxiang Ding, Dongxu Liu +3
Nonequilibrium many-body physics is one of the core problems in modern physics, while the dynamical scaling from a gapless phase to the critical point is a most important challenge…
Engineering quantum Mpemba effect by Liouvillian skin effect
Xiang Zhang, Chen Sun, Fuxiang Li
We propose a novel approach to engineer the quantum Mpemba effect (QME)-wherein an initial state farther from the steaty state relaxes faster than a closer one-by the Liouvillian s…
