Chern insulators, van Hove singularities and topological flat bands in magic-angle twisted bilayer graphene

Magic-angle twisted bilayer graphene exhibits intriguing quantum phase transitions triggered by enhanced electron–electron interactions when its flat bands are partially filled. However, the phases themselves and their connection to the putative non-trivial topology of the flat bands are largely une...
