Ordered states of undoped AB bilayer graphene: Bias-induced cascade of transitions (opens in new tab)

Author(s): A. V. Rozhkov, A. O. Sboychakov, and A. L. RakhmanovUsing mean field theory, we determine the electronic phase diagram of undoped AB-stacked bilayer graphene in the presence of a transverse electric field. In addition to multiple competing electronic instabilities characterized by excitonic order parameters, our framework incorporates the long-range …[Phys. Rev. B 113, 235421] Published Mon Jun 15, 2026
