Higher-order topology and fractional charge in monolayer graphene
Typical higher-order topological systems require the fine-tuning of hopping textures and external fields, which considerably hinders their practical realization. Based on a simple picture that corners are “edges” of edges, we determine that in the already-thoroughly-studied monolayer graphene, highe...
