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…

Evidence of two-dimensional macroscopic quantum tunneling of a current-biased DC-SQUID
F. Balestro, J. Claudon, J. P. Pekola +1
The escape probability out of the superconducting state of a hysteretic DC-SQUID has been measured at different values of the applied magnetic flux. At low temperature, the escape…
