| 英文摘要 | We theoretically study the superconductivity in multiorbital superconductors based on a three-orbital tight-banding model. With appropriate values of the nearest-neighbor exchange J(1)(alpha beta) and the next-nearest-neighbor exchange J(2)(alpha beta), we find a two-dome structure in the T-c- n phase diagram: one dome in the doping range n < 3.9 where the superconducting (SC) state is mainly s(x2y2) component contributed by inter-orbital pairing, the other dome in the doping range 3.9 < n < 4.46 where the SC state is mainly s(x2y2)( )+ s(x2+y2) 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 J(1) and J(2) considerably affect the boundary of two SC domes.
