Superconducting phase-dependent force in SNS junctions with mobile scatterers

We calculate the quantum (Casimir-like) superconducting phase-dependent force acting on mobile scatterers in superconductor–normal metal–superconductor (SNS) junctions. Repulsive Casimir forces are predicted in short SNS junctions with nonequilibrium (inverse) Andreev level populations. An anomalous...

Zusammenfassung:We calculate the quantum (Casimir-like) superconducting phase-dependent force acting on mobile scatterers in superconductor–normal metal–superconductor (SNS) junctions. Repulsive Casimir forces are predicted in short SNS junctions with nonequilibrium (inverse) Andreev level populations. An anomalous (nonmonotonic) temperature dependence of the quantum force is found in long SNS junctions.
