Motion of a Chain of Vortices Under Different Conditions of Passing a Current Through a Josephson Junction Coupled to a Waveguide

Resumo

We obtain the current–voltage characteristics for the following three modes of current passing through a system consisting of a Josephson junction coupled to a waveguide: first, only through the waveguide; second, both through the junction and through the waveguide; and third, only through the junction. In the first and second modes, sustaining of the induced motion of fast vortex chains is possible at a lower current density than that in the third mode.
