Spin-Orbit-Induced Topological Flat Bands in Line and Split Graphs of Bipartite Lattices
Spin-Orbit-Induced Topological Flat Bands in Line and Split Graphs of Bipartite Lattices
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 transport. In this work, we introduce a generic approach to construct two-dimensional (2D) topological quasi-flat bands from line graphs and split graphs of bipartite lattices. …
