Shot-noise-driven escape in hysteretic Josephson junctions
J. P. Pekola, T. E. Nieminen, M. Meschke +3
We have measured the influence of shot noise on hysteretic Josephson junctions initially in macroscopic quantum tunnelling (MQT) regime. Escape threshold current into the resistive…

Observation of transition from escape dynamics to underdamped phase diffusion in a Josephson junction
J. M. Kivioja, T. E. Nieminen, J. Claudon +3
We have investigated the dynamics of underdamped Josephson junctions. In addition to the usual crossover between macroscopic quantum tunnelling and thermally activated (TA) behavio…
