Superconductivty without inversion symmetry: MnSi versus CePt_3Si

Strongly Correlated Electrons 2009-11-10 v3 Superconductivity

Abstract

Superconductivity in materials without spatial inversion symmetry is studied. We show that in contrast to common believe, spin-triplet pairing is not entirely excluded in such systems. Moreover, paramagnetic limiting is analyzed for both spin-singlet and triplet pairing. The lack of inversion symmetry reduces the effect of the paramagnetic limiting for spin-singlet pairing. These results are applied to MnSi and CePt_3Si.
