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…

Topological flat bands in hyperbolic lattices
Dong-Hao Guan, Lu Qi, Yuan Zhou +2
Topological flat bands (TFBs) provide a promising platform to investigate intriguing fractionalization phenomena, such as the fractional Chern insulators (FCIs). Most of TFB models…
