Abstract: 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. Copyright EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg 2015
