Hofstadter subband ferromagnetism and symmetry broken Chern insulators in twisted bilayer graphene
Published on June 11, 2021

Transport measurements of twisted bilayer graphene reveal a sequence of spin and valley polarized states with Chern numbers 1, 2, 3. We can understand these states using a Hartree theory on top of a Hofstadter butterfly.
