Superconducting Pairing Symmetry on the Extended Hubbard Model in the Presence of the Rashba-Type Spin--Orbit Coupling

Shigeta Keisuke , Onari Seiichiro , Tanaka Yukio

… In order to study the pairing symmetry in non-centrosymmetric superconductors, we solve the linearized Éliashberg's equation on the two-dimensional extended Hubbard model in the presence of the Rashba-type spin--orbit coupling (RSOC) within the random phase approximation. … On the basis of our analytical study, it is found that the admixture of the spin-singlet and spin-triplet components depends on not only the predominant pairing symmetry but also the dispersion relation and pairing interaction. …
