Ideal Bands in Tight-Binding Models
Lexu Zhao, Yang Ge, Shinsei Ryu +1
A band is called ideal when its Dirichlet functional saturates the topological lower bound. We study ideal bands in finite-band tight-binding models with conventional two-dimension…

Nematic Wigner crystals in rhombohedral multilayer graphene
Yang Ge, Ashwini Malviya, Ethan Angerhofer +2
Recent experiments have reported evidence for Wigner crystals (WCs) in rhombohedral graphene. Here, we investigate Wigner crystallization in rhombohedral tetralayer graphene using…
