The dc-Josephson effect with more than four superconducting leads
Régis Mélin
By definition, the -terminal dc-Josephson current is sensitive to the superconducting phase variables of terminals. In the paper, we establish protocol for direct detection…
Ultralong-distance quantum correlations in three-terminal Josephson junctions
Régis Mélin
The production of entangled pairs of electrons in ferromagnet-superconductor-ferromagnet or normal metal-superconductor-normal metal three-terminal structures has aroused considera…
Positive current cross-correlations in a highly transparent normal-superconducting beam splitter due to synchronized Andreev and inverse Andreev reflections
Axel Freyn, Martina Flöser, Régis Mélin
Predictions are established for linear differential current-current cross-correlations dSab/dV in a symmetrically biased three-terminal normal metal-superconductor-normal metal (NS…
Sign of the crossed conductances at a FSF double interface
R. Mélin, D. Feinberg
Crossed conductance in hybrid Ferromagnet / Superconductor / Ferromagnet (FSF) structures results from the competition between normal transmission and Andreev reflection channels.…
Transport properties of ferromagnet/d-wave superconductor/ferromagnet double junctions
N. Stefanakis, R. Mélin
We investigate transport properties of a trilayer made of a d-wave superconductor connected to two ferromagnetic electrodes. Using Keldysh formalism we show that crossed Andreev re…
Spin accumulation in FS junctions
R. Mélin, O. Bourgeois
We consider Andreev reflection in ferromagnet-superconductor junctions and extend the treatment by de Jong and Beenakker to incorporate the effect of a repulsive potential at the i…
Enhancement of Andreev reflection by spin polarization in out-of-equilibrium ferromagnet-superconductor junctions
O. Bourgeois, P. Gandit, J. Lesueur +4
We report on transport measurements on Nb/Al/Gd/Al/Nb junctions.Bulk Gadolinium is a weakly polarized ferromagnet (5-7%), and is present in the junction in granular form (superpara…
