✦ Synopsis

We consider a system of superconducting networks with constrictions in the junctions. It is argued that for a family of canonical scalings of the junction size the network can be modeled by a deGennes-Alexander energy functional plus an extra term that depends on the jump of the order parameter across the junction. The current equations for such junctions are a natural generalization of the Josephson condition for a standard weak link in a wire. The model is solved for a number of special network geometries.

In ultrasmall Josephson junctions where the charging energy exceeds the Josephson coupling energy, the usual supercurrent at zero voltage is completely suppressed. However, in the presence of environmental modes, stochastic tunneling of Cooper pairs leads to a current through the junction. For any s

Microwave irradiation of Nb-InAs-Nb single-junctions demonstrates that the half-integer Shapiro step is caused by ac nonequilibrium supercurrents. In addition, nonequilibrium dc supercurrents are observed as a conductance enhancement around zero bias. Both effects persist to temperatures integer Sha

When two superconductors are connected by a weak link a supercurrent flows determined by the difference in the macroscopic quantum phases of the superconductors. Originally, this phenomenon was discovered by Josephson [1] for the case of a weak link formed by a thin tunnel barrier. The supercurrent
