Observation of negative absolute resistance in a Josephson junction
J. Nagel, D. Speer, T. Gaber +7
We experimentally demonstrate the occurrence of negative absolute resistance (NAR) up to about in response to an externally applied dc current for a shunted Nb-Al/AlO-Nb…
Commensurability effects in superconducting Nb films with quasiperiodic pinning arrays
M. Kemmler, C. Guerlich, A. Sterck +5
We study experimentally the critical depinning current Ic versus applied magnetic field B in Nb thin films which contain 2D arrays of circular antidots placed on the nodes of quasi…
3-junction SQUID rocking ratchet
A. Sterck, R. Kleiner, D. Koelle
We investigate 3-junction SQUIDs which show voltage rectification if biased with an ac current drive with zero mean value. The Josephson phase across the SQUID experiences an effec…
Non-ideal artificial phase discontinuity in long Josephson 0-kappa-junctions
T. Gaber, E. Goldobin, A. Sterck +4
We investigate the creation of an arbitrary -discontinuity of the Josephson phase in a long Nb-AlO_x-Nb Josephson junction (LJJ) using a pair of tiny current injectors, and stud…
Dynamics of semifluxons in Nb long Josephson 0-pi junctions
E. Goldobin, A. Sterck, T. Gaber +2
We propose, implement and test experimentally long Josephson 0-pi junctions fabricated using conventional Nb-AlOx-Nb technology. We show that using a pair of current injectors, one…
Josephson vortex in a ratchet potential: Theory
E. Goldobin, A. Sterck, D. Koelle
We propose a new type of Josephson vortex ratchet. In this system a Josephson vortex moves in a periodic asymmetric potential under the action of a deterministic or random force wi…
