Journal ArticleDOI
Ground State and Hidden Symmetry of Magic-Angle Graphene at Even Integer Filling
Nick Bultinck,Eslam Khalaf,Shang Liu,Shubhayu Chatterjee,Ashvin Vishwanath,Michael P. Zaletel +5 more
TL;DR: In this article, the usual insulating behavior in twisted bilayer graphene can be explained by a symmetry breaking that arises when cells in the superlattice are filled with an even number of electrons.
Journal ArticleDOI
Mechanism for Anomalous Hall Ferromagnetism in Twisted Bilayer Graphene.
TL;DR: In this article, the authors use a lowest Landau level model to understand the origin of the underlying symmetry-broken correlated state of twisted bilayer graphene, which exhibits a phase transition from a spin-valley polarized insulator to a partial or fully valley unpolarized metal as the bandwidth is increased relative to the interaction strength.
Journal ArticleDOI
Triangular antiferromagnetism on the honeycomb lattice of twisted bilayer graphene
TL;DR: In this article, the electronic band structures of states with the same symmetry as the three-sublattice planar antiferromagnetic order of the triangular lattice were presented.

Anomalous Hall ferromagnetism in twisted bilayer graphene
TL;DR: A lowest Landau level model is used to understand the origin of the underlying symmetry-broken correlated state in twisted bilayer graphene, which exhibits a phase transition from a spin-valley polarized insulator to a partial or fully valley unpolarized metal as the bandwidth is increased relative to the interaction strength.
Journal ArticleDOI
Charged skyrmions and topological origin of superconductivity in magic-angle graphene.
Eslam Khalaf,Shubhayu Chatterjee,Nick Bultinck,Nick Bultinck,Michael P. Zaletel,Ashvin Vishwanath +5 more
TL;DR: In this article, a symmetry breaking condensate leads to the ordered insulator, while topological solitons in the condensates-skyrmions-are shown to be charge 2e bosons.
