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…
Semi-fluxons in long Josephson 0-pi-junctions
E. Goldobin, D. Koelle, R. Kleiner
We investigate analytically long Josephson junctions with phase pi-discontinuity points. Such junctions are usually fabricated as a ramp between a superconductor like YBCO with d-w…
