Giant magnetoconductivity in non-centrosymmetric superconductors

Abstract

We discuss a novel physical mechanism which gives rise to a giant magnetoconductivity in non-centrosymmetric superconducting films. This mechanism is caused by a combination of spin-orbit interaction and inversion symmetry breaking in the system, and arises in the presence of an in-plane magnetic field ${\mathbf{H}}_{\Vert }$. It produces a contribution to the conductivity, which displays a strong dependence on the angle between the electric field $\mathbf{E}$ and ${\mathbf{H}}_{\Vert }$, and is proportional to the inelastic relaxation time of quasiparticles. Since in typical situations the latter is much larger than the elastic one this contribution can be much larger than the conventional conductivity thus leading to giant microwave absorption.
