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 $\kappa$-discontinuity of the Josephson phase in a long Nb-AlO_x-Nb Josephson junction (LJJ) using a pair of tiny current injectors, and stud…
