Research paperTheoreticalKohn-–Luttinger like superconductivity in twisted bilayer graphene at large twist anglesA.O. SboychakovarXiv·2026·arXiv:2606.23308AbstractWe predict that twisted bilayer graphene with large twist angle and small superlattice cell can be superconducting. Such a bilayer graphene can have a gap in the spectrum. This gap appears due to the hybridization of electrons moving in different layers with Fermi momenta close to the Dirac points which are equivalent to each other in the superlattice Brillouin zone. Small doping of the bilayer introduces charge carries having large density of states. We show that the screened Coulomb interaction is enough to stabilize superconducting state in the material. The symmetry of the order parameter is of the d-wave type. Application of the bias voltage increases the superconducting transition temperature. For realistic values of the model parameters the transition temperature can be as large as several hundreds of milikelvin.Read more
