Superconductivity and spin density wave in AA stacked bilayer graphene
A. O. Sboychakov, A. L. Rakhmanov, A. V. Rozhkov
This work theoretically analyzes electronic ordering in AA-stacked bilayer graphene and the role of the Coulomb interaction in these many-body phenomena. Using the random phase app…
Simple model for the gap in the surface states of the antiferromagnetic topological insulator MnBiTe
R. S. Akzyanov, A. L. Rakhmanov
We study the influence of the antiferromagnetic order on the surface states of topological insulators. We derive an effective Hamiltonian for these states, taking into account the…
Coexistence of nematic superconductivity and spin density wave in magic-angle twisted bilayer graphene
A. O. Sboychakov, A. V. Rozhkov, A. L. Rakhmanov
We argue that doped twisted bilayer graphene with magical twist angle can become superconducting. In our theoretical scenario, the superconductivity coexists with the spin-density-…
Triplet superconductivity and spin density wave in biased AB bilayer graphene
A. O. Sboychakov, A. V. Rozhkov, A. L. Rakhmanov
We examine spin density wave and triplet superconductivity as possible ground states of the Bernal bilayer graphene. The spin density wave is stable for the unbiased and undoped bi…
Ordering in SU(4)-symmetric model of AA bilayer graphene
A. V. Rozhkov, A. O. Sboychakov, A. L. Rakhmanov
We examine possible ordered states of AA stacked bilayer graphene arising due to electron-electron coupling. We show that under certain assumptions the Hamiltonian of the system po…
Half-metal and other fractional metal phases in doped AB bilayer graphene
A. L. Rakhmanov, A. V. Rozhkov, A. O. Sboychakov +1
We theoretically argue that, in doped AB bilayer graphene, the electron-electron coupling can give rise to the spontaneous formation of fractional metal phases. These states, being…
