Quantum decay of the supercurrent and intrinsic capacitance of Josephson junctions beyond the tunnel limit

A nondissipative supercurrent state of a Josephson junction is metastable with respect to the formation of a finite-resistance state. This transition is driven by fluctuations, thermal at high temperatures and quantum at low temperatures. We evaluate the lifetime of such a state due to quantum fluct...
