Superconducting Josephson vortices have direct analogues in ultracold-atom physics as solitary-wave excitations of two-component superfluid Bose gases with linear coupling. Here we numerically extend the zero-velocity Josephson vortex solutions of the coupled Gross-Pitaevskii equations to non-zero velocities. thus obtaining the full dispersion relation. The inertial mass of the Joseph... https://www.socialstudiesscholar.com/
