Observation of higher-order time-dislocation topological modes
Jia-Hui Zhang, Feng Mei, Yi Li +4
Topological dislocation modes resulting from the interplay between spatial dislocations and momentum-space topology have recently attracted significant interest. Here, we theoretic…
Dynamical Detection of Topological Spectral Density
Jia-Hui Zhang, Feng Mei, Liantuan Xiao +1
Local density of states (LDOS) is emerging as powerful means of exploring synthetic topological phases. However, the current LDOS detection method remains rare and merely works for…
Topological optical Raman superlattices
Jia-Hui Zhang, Bei-Bei Wang, Feng Mei +3
Topological phases of ultracold atoms recently have been intensively studied both in optical superlattices and Raman lattices. However, the topological features induced by the inte…
Generalized Aubry-Andre-Harper Models in Optical Superlattices
Yi Li, Jia-Hui Zhang, Feng Mei +3
Ultracold atoms trapped in optical superlattices provide a simple platform for realizing the seminal Aubry-André-Harper (AAH) model. However, the periodic modulations on the neares…
