Surface bound states and spin currents in non-centrosymmetric superconductors
A. B. Vorontsov, I. Vekhter, M. Eschrig
We investigate the influence of spin-orbit coupling in a non-centrosymmetric superconductor on its ground state properties near a surface. We determine the spectrum of Andreev boun…
0-pi Transitions in a Superconductor/Chiral Ferromagnet/Superconductor Junction induced by a Homogeneous Cycloidal Spiral
Thierry Champel, Tomas Löfwander, Matthias Eschrig
We study the pi phase in a superconductor-ferromagnet-superconductor Josephson junction, with a ferromagnet showing a cycloidal spiral spin modulation with in-plane propagation vec…
Theory of vortices in hybridized ballistic/diffusive-band superconductors
K. Tanaka, M. Eschrig, D. F. Agterberg
We study the electronic structure in the vicinity of a vortex in a two-band superconductor in which the quasiparticle motion is ballistic in one band and diffusive in the other. Th…
Effect of an inhomogeneous exchange field on the proximity effect in disordered superconductor-ferromagnet hybrid structures
T. Champel, M. Eschrig
We investigate the effect of an inhomogeneous exchange field on the proximity effect in superconductor-ferromagnet hybrid structures within the quasi-classical theory of supercondu…
Switching superconductivity in S/F bilayers by multiple-domain structures
T. Champel, M. Eschrig
We consider the effect of a multiple magnetic domain structure in a superconductor/ferromagnet bilayer, modeled by a ferromagnetic layer with a rotating magnetic moment. The domain…
Singlet-Triplet Mixing in Superconductor-Ferromagnet Hybrid Devices
M. Eschrig, J. Kopu, A. Konstandin +3
We develop a theory which describes hybrid structures consisting out of superconducting and ferromagnetic parts. We give two examples for applications. First, we consider a hybrid…
