Hofstadter subband ferromagnetism in twisted bilayer graphene

The beautiful measurements of Yu Saito and Andrea Young display clear Chern insulator states. The sequence of C=-1, -2, -3, -4 states from the left can be understood as arising from spontaneous valley and spin polarization.

Together with the Yu Saito and Andrea Young (UC Santa Barbara) we wrote a paper about symmetry broken states in the presence of large magnetic fields in twisted bilayer graphene.

Read here more about it, on the arXiv.
