Ground State and Hidden Symmetry of Magic-Angle Graphene at Even Integer Filling
Ground State and Hidden Symmetry of Magic-Angle Graphene at Even Integer Filling
In magic angle twisted bilayer graphene, electron-electron interactions play a central role resulting in correlated insulating states at certain integer fillings. Identifying the nature of these insulators is a central question and potentially linked to the relatively high temperature superconductivity observed in the same devices. Here we address this question …
