Fragile topology in line-graph lattices with two, three, or four gapped flat bands
Christie S. Chiu, Da-Shuai Ma, Zhi-Da Song +2
The geometric properties of a lattice can have profound consequences on its band spectrum. For example, symmetry constraints and geometric frustration can give rise to topologicial…

Spin-Orbit-Induced Topological Flat Bands in Line and Split Graphs of Bipartite Lattices
Da-Shuai Ma, Yuanfeng Xu, Christie S. Chiu +4
Topological flat bands, such as the band in twisted bilayer graphene, are becoming a promising platform to study topics such as correlation physics, superconductivity, and transpor…
