Quasiparticles of widely tuneable inertial mass: The dispersion relation of atomic Josephson vortices and related solitary waves
Superconducting Josephson vortices have direct analogues in ultracold-atom physics as solitary-wave excitations of two-component Aloe Vera 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 disper
