Thermal depinning of fluxons in ratchet discrete Josephson rings

Naranjo, F. ; Segall, K. ; Mazo, J.J. (Universidad de Zaragoza)

Resumen: We study numerically the thermal depinning of single fluxons in ratchet Josephson junction rings. Rings are made of 9 junctions with 3 different critical currents. We present results for a wide range of the main physical parameters of the system: damping, coupling and temperature. The computed results can be well understood in the framework of single particle thermal activation theories.
