Existence, Uniqueness and Multiplicity of Rotating Fluxon Waves in Annular Josephson Junctions
نویسنده
چکیده
We prove that the equation modelling an annular Josephson junction has a rotating fluxon wave solution for all values of the parameters. We also obtain results on uniqueness of the rotating fluxon wave in some parameter regimes, and on multiplicity of rotating fluxon waves in other parameter regimes.

Fluxon motion in one-dimensional Josephson junction arrays
Current-voltage ( I V ) characteristics of linear and annular discrete arrays of underdamped small Josephson junctions with different values of single loop inductances are calculated numerically and compared with those obtained for continuum long Josephson junctions. The resonances between the moving fluxon and the linear waves caused by the array discreteness induce steps on t h e / V c u r v ...
متن کاملAnnular Long Josephson Junctions in a Magnetic Field: Engineering and Probing the Fluxon Interaction Potential
The interaction of a Josephson fluxon with an external magnetic field-induced potential in a long Josephson junction is investigated experimentally. The thermal activation of the fluxon from a potential well is observed and experiments probing its predicted quantum properties are discussed. A method for engineering a magnetic double-well potential for a fluxon is proposed and the use of the cou...
