Description:
Author(s): Dong Wang, Zhao Liu, Wu-Ming Liu, Junpeng Cao, and Heng Fan We study fermions on a triangular lattice model that exhibits topological flatbands characterized by nonzero Chern numbers. Our scheme stems from the well-known Hofstadter model but the next-nearest-neighbor hopping is introduced, which is crucial for tuning the lowest band to be nearly flat. Differ... [Phys. Rev.
