Thermal depinning of fluxons in ratchet discrete Josephson rings 2015 Access copy available to the general public Unrestricted 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. info:eu-repo/grantAgreement/ES/DGA/FENOL-GROUP info:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.223 2015 PHYSICS, CONDENSED MATTER 47 / 67 = 0.701 2015 Q3 T3 0.514 2015 Electronic, Optical and Magnetic Materials 2015 Q2 Condensed Matter Physics 2015 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Segall, K.
