Orbital driven two-dome superconducting phases in multiorbital superconductors

Abstract
We theoretically study the superconductivity in multiorbital superconductors based on a three-orbital tight-banding model. With appropriate values of the nearest-neighbour exchange and the next-nearest-neighbour exchange , we find a two-dome structure in the phase diagram: one dome in the doping range where the superconducting (SC) state is mainly component contributed by inter-orbital pairing, the other dome in the doping range where the SC state is mainly components contributed by intra-orbital pairing. We find that the competition between different orbital pairing leads to two-dome SC phase diagrams in multiorbital superconductors, and different matrix elements of and considerably affect the boundary of two SC domes.
