Dual Josephson phenomena with vortices
Department of Electrical Engineering and Electronics University of Liverpool, Brownlow Hill - Liverpool L69 3GJ, UK
Accepted: 20 August 1999
A dual quantum interference device (DQUID) is considered, made from a ring with circulating vortices and a weak link. A current feeds the center of the ring with a time-dependent charge . The dual Josephson equations which describe macroscopically the tunelling of vortices through the weak link are derived. Various types of the current are considered and the dual Josephson equations are solved.
