Ground State and Hidden Symmetry of Magic Angle Graphene at Even Integer Filling
Nick Bultinck, Eslam Khalaf, Shang Liu +3
In magic angle twisted bilayer graphene, electron-electron interactions play a central role resulting in correlated insulating states at certain integer fillings. Identifying the n…
Nematic topological semimetal and insulator in magic angle bilayer graphene at charge neutrality
Shang Liu, Eslam Khalaf, Jong Yeon Lee +1
We report on a fully self-consistent Hartree-Fock calculation of interaction effects on the Moiré flat bands of twisted bilayer graphene, assuming that valley U(1) symmetry is resp…
Theory of correlated insulating behaviour and spin-triplet superconductivity in twisted double bilayer graphene
Jong Yeon Lee, Eslam Khalaf, Shang Liu +4
Two monolayers of graphene twisted by a small `magic' angle exhibit nearly flat bands leading to correlated electronic states and superconductivity, whose precise nature including…
