Tuning anomalous Floquet topological bands with ultracold atoms
Jin-Yi Zhang, Chang-Rui Yi, Long Zhang +7
The Floquet engineering opens the way to create new topological states without counterparts in static systems. Here, we report the experimental realization and characterization of…

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…

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…
