Square lattice model with staggered magnetic fluxes: zero Chern number topological states and topological flat bands
Li-Xiang Chen, Dong-Hao Guan, Lu Qi +3
Staggered magnetic fluxes (SMF) play a crucial role in achieving Chern insulators (CIs), by which a series of CI models have been established on various lattices. In addition, SMF…

Hyperbolic Fractional Chern insulators
Ai-Lei He, Lu Qi, Yongjun Liu +1
Fractional Chern insulators (FCIs) have attracted intensive attention for the realization of fractional quantum Hall states in the absence of an external magnetic field. Most of FC…
