Abstract

The effect of single-pair-tunneling on the equilibrium state of tunnel junctions is investigated. We study analytically the free energy of quantum phase fluctuations originated by quantized charging of the tunnel capacitor. Feynman path-integral methods are applied to a quantum particle in a periodic potential. The temperature dependence of the critical current is found to be a convex function; the maximum appears at finite temperature indicating a saturation effect which results from a competition between the Coulomb gap and the thermal energy.
