Photonic realization of a generic type of graphene edge states exhibiting topological flat band

Shiqi Xia, Yongsheng Liang, Liqin Tang +3

Cutting a honeycomb lattice (HCL) can end up with three types of edges (zigzag, bearded and armchair), as is well known in the study of graphene edge states. Here we theoretically…
