Spontaneous symmetry breaking and Lifshitz transition in bilayer graphene

Year: 2010

Type: article

Abstract: We derive the renormalization-group equations describing all the short-range interactions in bilayer graphene allowed by symmetry, the long-range Coulomb interaction, and band-structure parameters. For certain range of parameters, we predict the first-order phase transition to the uniaxially deformed gapless state accompanied by the change in the topology of the electron spectrum.
