Band structure of twisted bilayer graphene: Emergent symmetries, commensurate approximants, and Wannier obstructions
A remarkable feature of the band structure of bilayer graphene at small twist angle is the appearance of isolated bands near neutrality, whose bandwidth can be reduced at certain magic angles (e.g. θ∼1.05[superscript ∘]). In this regime, correlated insulating states and superconductivity have been e...
