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…
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…
Restoring Kibble-Zurek Scaling and Defect Freezing in Non-Hermitian Systems under Biorthogonal Framework
Menghua Deng, Wei Li, Kangyi Hu +1
Non-Hermitian physics provides an effective description of open and nonequilibrium systems and hosts many novel and intriguing phenomena such as exceptional points and non-Hermitia…
Universal scaling of quantum state transport in one-dimensional topological chain under nonadiabatic dynamics
Lingzi Huang, Menghua Deng, Chen Sun +1
When a system is driven across a continuous phase transition, the density of topological defects demonstrates a power-law scaling behavior versus the quenching rate, as predicted b…
Scaling of quantum Fisher information for quantum exceptional point sensors
Chun-Hui Liu, Fu Li, Shengwang Du +3
In recent years, significant progress has been made in utilizing the divergence of spectrum response rate at the exceptional point (EP) for sensing in classical systems, while the…
Solution to a class of multistate Landau-Zener model beyond integrability conditions
Rongyu Hu, Fuxiang Li, Chen Sun
We study a class of multistate Landau-Zener model which cannot be solved by integrability conditions or other standard techniques. By analyzing analytical constraints on its scatte…
Singularity of classical and quantum correlations at critical points of the Lipkin-Meshkov-Glick model in bipartition and tripartition of spins
Zhang Xiu-Xing, Li Fu-Li
We study the classical correlation (CC) and quantum discord (QD) between two spin subgroups of the Lipkin-Meshkov-Glick (LMG) model in both binary and trinary decompositions of spi…
