Exciton condensation in biased bilayer graphene
We consider suspended bilayer graphene under applied perpendicular electric bias field that is known to generate a single particle gap 2Δ and a related electric polarization P. We argue that the bias also drives a quantum phase transition from band insulator to superfluid exciton condensate. The tra...
