Proximity effect in noncentrosymmetric superconductors hybrid structures — •Gaetano Annunziata1, Jacob Linder2, and Dirk Manske1 — 1Max-Planck-Institut für Festkörperforschung, Heisenbergstrasse 1, D-70569 Stuttgart, Germany — 2Department of Physics, Norwegian University of Science and Technology, N-7491 Trondheim, Norway
We analyze proximity effect in junctions of noncentrosymmetric superconductors (NCSs) and diffusive metals/ferromagnets within the quasiclassical theory of superconductivity. We show how by standard STM/STS measurements for LDOS in the proximate region [1] exploiting the directional dependence of pair-breaking effect of the exchange field on the triplet Cooper pairs [2,3], several superconducting scenarios for NCSs characterized by different kinds of edge states [4] can be discriminated, and that within a single scenario information on the relative magnitude of triplet and singlet gaps in NCSs can be obtained [5].
