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…

Observation of the Hopf Links and Hopf Fibration in a 2D topological Raman Lattice
Chang-Rui Yi, Jin-Long Yu, Wei Sun +3
A dynamical Hopf insulator is experimentally synthesized with a quenched two-dimensional quantum anomalous Hall system on a square Raman lattice. The quench dynamics for the quasim…

Uncover Topology by Quantum Quench Dynamics
Wei Sun, Chang-Rui Yi, Bao-Zong Wang +9
Topological quantum states are characterized by nonlocal invariants, and their detection is intrinsically challenging. Various strategies have been developed to study topological H…
