Title: Long-range Josephson effect in mesoscopic T-shaped superconductor–normal-metal–superconductor junctions

At finite temperature, this nonequilibrium Josephson current is proportional to the applied voltage and saturates at $\mathrm{eV}>\ensuremath{\Delta}$ at a level typical for the critical current of short junctions. In asymmetric junctions the current-phase dependence is \ensuremath{\pi} periodic.Read More
