Thermal Escape from a Metastable State in Periodically Driven Josephson Junctions
arXiv:cond-mat/0602401 · doi:10.1103/PhysRevE.75.021107
Abstract
Resonant activation and noise-enhanced stability were observed in an underdamped real physical system, i.e., Josephson tunnel junctions. With a weak sinusoidal driving force applied, the thermal activated escape from a potential well underwent resonance-like behavior as a function of the driving frequency. The resonance also crucially depended on the initial condition of the system. Numerical simulations showed good agreement with the experimental results.
