# Singlet-quintet mixing in spin-orbit coupled superconductors with j=32 fermions

@article{Yu2018SingletquintetMI, title={Singlet-quintet mixing in spin-orbit coupled superconductors with j=32 fermions}, author={Jiabin Yu and Chaoxing Liu}, journal={Physical Review B}, year={2018} }

In non-centrosymmetric superconductors, spin-orbit coupling can induce an unconventional superconducting state with a mixture of s-wave spin-singlet and p-wave spin-triplet channels, which leads to a variety of exotic phenomena, including anisotropic upper critical field, magnetoelectric effect, topological superconductivity, et al. It is commonly thought that inversion symmetry breaking is substantial for pairing-mixed superconducting states. In this work, we theoretically propose that a new…
