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…
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…
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…
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…
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…
Kibble-Zurek Behavior in the Boundary-obstructed Phase Transitions
Menghua Deng, Zhoujian Sun, Fuxiang Li
We study the nonadiabatic dynamics of a two-dimensional higher-order topological insulator when the system is slowly quenched across the boundary-obstructed phase transition, which…
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…
Broadband spectroscopy of thermodynamic magnetization fluctuations through a ferromagnetic spin-reorientation transition
A. L. Balk, F. Li, I. Gilbert +3
We use scanning optical magnetometry to study the broadband frequency spectra of spontaneous magnetization fluctuations, or "magnetization noise", in an archetypal ferromagnetic fi…
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…
