Cooperon condensation and intravalley pairing states in honeycomb Dirac systems
Cooperon condensation and intravalley pairing states in honeycomb Dirac systems
Motivated by recent developments in the experimental study of superconducting graphene and transition metal dichalcogenides, we investigate superconductivity of the Kane-Mele (KM) model with short-range attractive interactions on the two-dimensional honeycomb lattice. We show that intra-valley spin-triplet pairing arises from nearest-neighbor (NN) attractive interaction and the intrinsic spin-orbit coupling. We …
