 Recent experiments on magic angle twisted bilayer graphene have revealed a variety of new electronic phases driven by interactions between spin orbit coupling and valley polarization. These include an anomalous Hall effect, liftships transitions, and a quantum Hall effect which can be tuned by varying carrier density and magnetic field strength. At low carrier densities, the system exhibits partial valley polarization, while at higher densities it becomes fully valley polarized. This study demonstrates how singularities in the flat bands caused by spin orbit coupling can lead to the formation of ordered phases even when the moir band is partially filled.
