Triplet superconducting correlations: Magnet-superconductor hybrid structures in nonequilibrium — •Kevin Marc Seja1, Oleksii Shevtsov2, and Tomas Löfwander11Chalmers University of Technology, Göteborg, Sweden — 2Northwestern University, Evanston (IL), United States

We examine a superconductor that is in contact with a normal metal via a spin-active interface. Using quasiclassical theory of superconductivity, we study the system in equilibrium as well as in nonequilibrium induced by a voltage bias. Earlier investigations have shown that in equilibrium the interface gives rise to Andreev bound states that induce a spin magnetization in the supercon- ductor. It was found that this equilibrium magnetization is related to non- trivial triplet superconducting correlations, a key feature of unconventional superconductivity. Out of equilibrium there is an additional contribution to spin imbalance related to spin-filtering and spin-mixing mechanisms. [1,2] However, in non-equilibrium the possible connection between magnetization and superconducting triplet correlations is not yet understood. We examine this relation, the change in distribution as well as the structure and spatial behavior of these correlations in non-equilibrium configurations.
