Effects of impurities on Hc2(T) in superconductors without inversion symmetry

Abstract

We calculate the upper critical field, Hc2(T), due to the orbital pair breaking in disordered superconductors without inversion symmetry. Differences from the usual centrosymmetric case are highlighted. The linearized gap equations in magnetic field, with the singlet and triplet pairing channels mixed by impurity scattering, are solved exactly for a cubic crystal.
