Dynamic stabilization of a microwave-driven Josephson tunnel junction against a period-doubling bifurcation

We present theoretical and experimental results on the effect of periodic perturbations on microwave-driven Josephson tunnel junctions close to a period-doubling bifurcation. The theory, which is quite general, describes how a periodic near-resonant perturbation changes the stability of the system. The phenomenon was investigated experimentally in small Nb-NbOx-Pb tunnel junctions and found to ...

Influence of Thermal Fluctuations on an Underdamped Josephson Tunnel Junction

Inspired by a recent experiment, we study the influence of thermal fluctuations on the I-V characteristics of a Josephson junction, coupled to a strongly resistive environment. We obtain analytical results in the limit where the Josephson energy is larger than the charging energy and quasiparticles are absent.
