The Vortex State and Josephson Critical Current of a Diffusive SNS Junction
We study theoretically the electronic and transport properties of a diffusive superconductor-normal metal-superconductor (SNS) junction in the presence of a perpendicular magnetic field. We show that the field dependence of the critical current crosses over from the well-known Fraunhofer pattern in wide junctions to a monotonic decay when the width of the normal wire is smaller than the magneti...
متن کاملJosephson current and multiple Andreev reflections in graphene SNS junctions
The Josephson effect and superconducting proximity effect were observed in superconductor-graphenesuperconductor SGS Josephson junctions with coherence lengths comparable to the distance between the superconducting leads. By comparing the measured gate dependence of the proximity induced subgap features multiple Andreev reflections and of the supercurrent to theoretical predictions, we find tha...
متن کاملPhase Dependent Current Statistics in Short-arm Andreev Interferometer
We calculate analytically the current statistics for a short diffusive wire between the normal reservoir and a short superconductor-normal metal-superconductor (SNS) junction, at arbitrary applied voltages and temperatures. The cumulantgenerating function oscillates with the phase difference φ across the junction, approaching the normal-state value at φ = π. At T = 0 and at the applied voltage ...

متن کاملAndreev current-induced dissipation in a hybrid superconducting tunnel junction.
We have studied hybrid superconducting microcoolers made of a double superconductor-insulator-normal metal tunnel junction. Under subgap conditions, the Andreev current is found to dominate the single-particle tunnel current. We show that the Andreev current introduces additional dissipation in the normal metal equivalent to Joule heating. By analyzing quantitatively the heat balance in the sys...
