Interaction-Driven Topological Switch in a -Band Honeycomb Lattice
Hua Chen, X. C. Xie
The non-interacting band structure of spinless fermions in a two-dimensional () -band honeycomb lattice exhibits two quadratic band touching points (QBTPs), which lie at th…
Effects of random domains on the zero Hall plateau in quantum anomalous Hall effect
Chui-Zhen Chen, Haiwen Liu, X. C. Xie
Recently, a zero Hall conductance plateau with random domains is experimentally observed in quantum anomalous Hall (QAH) effect. We study the effects of random domains on the zero…
Crystalline Splitting of Orbitals in Regular Optical Lattices
Hua Chen, X. C. Xie
In solids, crystal field splitting refers to the lifting of atomic orbital degeneracy by the surrounding ions through the static electric field. Similarly, we show that the degener…
Anisotropic Magnetotransport and Exotic Longitudinal Linear Magnetoresistance in WTe2 Crystals
Yanfei Zhao, Haiwen Liu, Jiaqiang Yan +11
WTe2 semimetal, as a typical layered transition-metal dichalcogenide, has recently attracted much attention due to the extremely large, non-saturating parabolic magnetoresistance i…
