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…
Exact Work Distribution and Jarzynski's Equality of a Relativistic Particle in an Expanding Piston
Xianghang Zhang, Tingzhang Shi, H. T. Quan
We study the non-equilibrium work in a pedagogical model of relativistic ideal gas. We obtain the exact work distribution and verify the Jarzynski's equality. In the non-relativist…
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…
