Abstract

Recent experiments by Iansiti et al. (1989) on small Josephson junctions display various novel features: a finite resistance R0 associated with the low-voltage state, the co-existence of Coulomb blockade and Josephson tunnelling, . . . Since the existence of R0 cannot he explained by the simple RSJ model, nor by any classical model at low-temperatures, the authors adopt a quantum Langevin equation approach which incorporates frequency-dependent dissipation as well as dissipative quantum tunnelling. They obtain good agreement between their theory and the results of Iansiti et al. which reflects the influence of the environment.
