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…
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…
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…
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…
Activating non-Hermitian skin modes by parity-time symmetry breaking
Zhoutao Lei, Ching Hua Lee, Linhu Li
Parity-time () symmetry is a cornerstone of non-Hermitian physics as it ensures real energies for stable experimental realization of non-Hermitian phenomena. In this…
Tunable symmetry-protected higher-order topological states with fermionic atoms in bilayer optical lattices
Zhoutao Lei, Linhu Li, Yuangang Deng
Higher-order topological states that possess gapped bulk energy bands and exotic topologically protected boundary states with at least two dimension lower than the bulk have signif…
Topological classification of Higher-order topological phases with nested band inversion surfaces
Zhoutao Lei, Yuangang Deng, Linhu Li
Higher-order topological phases (HOTPs) hold gapped bulk bands and topological boundary states localized in boundaries with codimension higher than one. In this paper, we provide a…
Magnon boundary states tailored by longitudinal spin-spin interactions and topology
Wenjie Liu, Yongguan Ke, Zhoutao Lei +1
Since longitudinal spin-spin interaction is ubiquitous in magnetic materials, it is very interesting to explore the interplay between topology and longitudinal spin-spin interactio…
Unpaired topological triply degenerate point for spin-tensor-momentum-coupled ultracold atoms
Zhoutao Lei, Yuangang Deng, Chaohong Lee
The realization of triply degenerate points (TDPs) with exotic fermionic excitations has opened a new perspective for the understanding of our nature. Here we explore the coexisten…
Symmetry-Protected Topological Phase for Spin-Tensor-Momentum-Coupled Ultracold Atoms
Zhoutao Lei, Yuangang Deng, Chaohong Lee
We propose a realizable experiment scheme to construct a one-dimensional synthetic magnetic flux lattice with spin-tensor-momentum coupled spin-1 atoms and explore its exotic topol…
