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…
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…
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…
