High efficiency deterministic Josephson Vortex Ratchet
M. Beck, E. Goldobin, M. Neuhaus +3
We investigate experimentally a Josephson vortex ratchet -- a fluxon in an asymmetric periodic potential driven by a deterministic force with zero time average. The highly asymmetr…
Quantum tunneling of semifluxons
E. Goldobin, K. Vogel, O. Crasser +4
We consider a system of two semifluxons of opposite polarity in a 0-pi-0 long Josephson junction, which classically can be in one of two degenerate states: up-down or down-up. When…
Controllable plasma energy bands in a 1D crystal of fractional Josephson vortices
H. Susanto, E. Goldobin, D. Koelle +2
We consider a 1D chain of fractional vortices in a long Josephson junction with alternating phase discontinuities. Since each vortex has its own eigenfrequency, the inter-vo…
Oscillatory eigenmodes and stability of one and two arbitrary fractional vortices in long Josephson 0-kappa-junctions
E. Goldobin, H. Susanto, D. Koelle +2
We investigate theoretically the eigenmodes and the stability of one and two arbitrary fractional vortices pinned at one and two -phase discontinuities in a long Josephson junct…
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…
