We apply cluster dynamical mean field theory with an exact-diagonalization impurity solver to a Hubbard model for magic-angle twisted bilayer graphene, built on the tight-binding model proposed by Kang and Vafek (2018), which applies to the magic angle 1.30∘. We find that triplet superconductivity with p+ip symmetry is stabilized by CDMFT, as well as a subdominant singlet d+id state. A minimum of the order parameter exists close to quarter-filling and three-quarter filling, as observed in experiments.
