Occupation-selective topological pumping from Floquet gauge fields
Wenjie Liu, Ching Hua Lee, Zhoutao Lei
Topological pumping is conventionally governed by single-particle band topology. Here we show that promoting tunneling to a dynamical, occupation-conditioned variable fundamentally…
Inter-species topological phases via a dynamical gauge field
Zhoutao Lei, Linhu Li
We uncover a class of inter-species topological phases in a one-dimensional lattice, loaded with two species of non-identical particles interacting via a dynamical gauge field (DGF…
Diagnosing Floquet Chern and anomalous topological insulators based on Bloch oscillations
Maowu Zuo, Yongguan Ke, Zhoutao Lei +1
It is challenging to distinguish Floquet Chern insulator (FCI) and Floquet anomalous topological insulator (FATI) because of their common features of chiral edge states and far awa…
Topological Dynamics and Correspondences in Composite Exceptional Rings
Zhoutao Lei, Yuangang Deng
The study of unconventional phases and elucidation of correspondences between topological invariants and their intriguing properties are pivotal in topological physics. Here, we in…
