Accurate tight-binding model for twisted bilayer graphene describes topological flat bands without geometric relaxation
A major hurdle in understanding the phase diagram of twisted bilayer graphene is the roles of lattice relaxation and electronic structure on isolated band flattening near magic twist angles. In this work, the authors develop an accurate local environment tight-binding model fit to tight-binding para...
