Dynamical characterization of Floquet topological phases via quantum quenches
Lin Zhang
The complete characterization of a generic -dimensional Floquet topological phase is usually hard for the requirement of information about the micromotion throughout the entire…
Unified characterization for higher-order topological phase transitions
Wei Jia, Xin-Chi Zhou, Lin Zhang +2
Higher-order topological phase transitions (HOTPTs) are associated with closing either the bulk energy gap (type-I) or boundary energy gap (type-II) without changing symmetry, and…
Experimental quantum simulation of non-Hermitian dynamical topological states using stochastic Schrödinger equation
Zidong Lin, Lin Zhang, Xinyue Long +8
Noise is ubiquitous in real quantum systems, leading to non-Hermitian quantum dynamics, and may affect the fundamental states of matter. Here we report in experiment a quantum simu…
Dynamical detection of mean-field topological phases in an interacting Chern insulator
Wei Jia, Long Zhang, Lin Zhang +1
Interactions generically have important effects on the topological quantum phases. For a quantum anomalous Hall (QAH) insulator, the presence of interactions can qualitatively chan…
Universal topological quench dynamics: Altland-Zirnbauer tenfold classes
Lin Zhang, Wei Jia, Xiong-Jun Liu
Topological phases of the famous Altland-Zirnbauer (AZ) tenfold classes are defined on the equilibrium ground states. Whether such equilibrium topological phases have universal cor…
Dynamically characterizing topological phases by high-order topological charges
Wei Jia, Lin Zhang, Long Zhang +1
We propose a new theory to characterize equilibrium topological phase with non-equilibrium quantum dynamics by introducing the concept of high-order topological charges, with novel…
Stability of dynamical topology against dynamical noise in quantum quenches
Lin Zhang, Long Zhang, Xiong-Jun Liu
Equilibrium topological phases are robust against weak static disorder but may break down in the strong disorder regime. Here we explore the stability of the quench-induced emergen…
Quantum dynamical characterization and simulation of topological phases with high-order band inversion surfaces
Xiang-Long Yu, Wentao Ji, Lin Zhang +3
How to characterize topological quantum phases is a fundamental issue in the broad field of topological matter. From a dimension reduction approach, we propose the concept of high-…
Unified theory to characterize Floquet topological phases by quench dynamics
Long Zhang, Lin Zhang, Xiong-Jun Liu
The conventional characterization of periodically driven systems usually necessitates the time-domain information beyond Floquet bands, hence lacking universal and direct schemes o…
Quantum simulation for three-dimensional chiral topological insulator
Wentao Ji, Lin Zhang, Mengqi Wang +8
Quantum simulation, as a state-of-art technique, provides the powerful way to explore topological quantum phases beyond natural limits. Nevertheless, a previously-not-realized thre…
Characterizing topological phases by quantum quenches: A general theory
Long Zhang, Lin Zhang, Xiong-Jun Liu
We investigate a generic dynamical theory to characterize topological quantum phases by quantum quenches, and study the emergent topology of quantum dynamics when the quenches star…
Observing topological charges and dynamical bulk-surface correspondence with ultracold atoms
Chang-Rui Yi, Long Zhang, Lin Zhang +8
In quenching a topological phase across phase transition, the dynamical bulk-surface correspondence emerges that the bulk topology of -dimensional (D) phase relates to the no…
Emergent topology and symmetry-breaking order in correlated quench dynamics
Long Zhang, Lin Zhang, Ying Hu +2
Quenching a quantum system involves three basic ingredients: the initial phase, the post-quench target phase, and the non-equilibrium dynamics which carries the information of the…
Dynamical detection of topological charges
Long Zhang, Lin Zhang, Xiong-Jun Liu
We propose a generic scheme to characterize topological phases via detecting topological charges by quench dynamics. A topological charge is defined as the chirality of a monopole…
Dynamical classification of topological quantum phases
Lin Zhang, Long Zhang, Sen Niu +1
Topological phase of matter is now a mainstream of research in condensed matter physics, of which the classification, synthesis, and detection of topological states have brought ex…
A generic theory for Majorana zero modes in 2D superconductors
Cheung Chan, Lin Zhang, Ting Fung Jeffrey Poon +3
It is well known that non-Abelian Majorana zero modes (MZM) harbor at vortex cores in a topological superconductor, which can be realized in a 2D spin-orbit c…
