Nonlocal electrodynamics of long ultra-narrow Josephson junctions: Experiment and theory

A. A. Abdumalikov, V. V. Kurin, C. Helm +3

We experimentally and theoretically investigate electromagnetic cavity modes in ultra-narrow Al-AlO${}_x$-Al and Nb-AlO${}_x$-Nb long Josephson junctions. Experiments show that the vol…
