Global phase diagram of charge-neutral graphene in the quantum Hall regime for generic interactions
Global phase diagram of charge-neutral graphene in the quantum Hall regime for generic interactions
Monolayer graphene at charge neutrality in a quantizing magnetic field is a quantum Hall ferromagnet. Due to the spin and valley (near) degeneracies, there is a plethora of possible ground states. Previous theoretical work, based on a stringent ultra short-range assumption on the symmetry-allowed interactions, predicts a phase diagram with …
