Abstract:

In materials with no spatial inversion symmetry, the antisymmetric spin-orbit coupling can cause an admixture of the spin-singlet and spin-triplet pairings. We study the influence of the spin-orbit coupling and the degree of parity mixing on the specific heat and spin susceptibility of such superconductors, with a particular emphasis on the heavy fermion superconductor CePt3Si. Results compatible with experimental findings are obtained.

Key words: CePt3Si, noncentrosymmetric superconductor, specific heat, spin susceptibility, parity mixing effects
