Abstract

The effect of spatial inhomogeneity on the properties of a two-dimensional noncentrosymmetric superconductor in an in-plane magnetic field is investigated, as it can be realized in LaAlO(3)-SrTiO(3) interfaces. We demonstrate that the spatial variation of Rashba spin-orbit coupling yields a local magnetic flux pattern due to the field-induced inhomogeneous helical phase. For sufficiently strong fields, vortices can nucleate at inhomogeneities of the Rashba spin-orbit coupling.
