Spontaneous layer polarization and conducting domain walls in the quantum Hall regime of bilayer graphene
Spontaneous layer polarization and conducting domain walls in the quantum Hall regime of bilayer graphene
Bilayer graphene subjected to perpendicular magnetic and electric fields displays a subtle competition between different symmetry-broken phases, resulting from an interplay between the internal spin and valley degrees of freedom. The transition between different phases is often identified by an enhancement of the conductance. Here, we propose that the enhanced …
