Singlet and triplet BCS pairs in a gas of two-species fermionic polar molecules
arXiv:0910.4051 · doi:10.1103/PhysRevA.82.033623
Abstract
We investigate the BCS pairing in a mixture of fermionic polar molecules with two different hyperfine states. We derive a set of coupled gap equations and find that this system supports both spin-singlet and -triplet BCS pairs. We also calculate the critical temperatures and the angular dependence of order parameters. In addition, by tuning short-range interaction between inter-species molecules, the transition between singlet and triplet paired states may be realized.
