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…

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…

Unique and Universal scaling in dynamical quantum phase transitions
Xiang Zhang, Liangdong Hu, Fuxiang Li
Universality and scaling are fundamental concepts in equilibrium continuous phase transitions. Here, we unveil a unique and universal scaling behavior of the critical time in slowl…
