Abstract

The hydrodynamics of quantized vortices and solitons in an atomic Bose-Einstein condensate excited by an oscillating potential are studied by numerically solving the two-dimensional Gross-Pitaevskii equation. The oscillating potential keeps nucleating vortex dipoles, whose impulses alternatively change their direction synchronously with the oscillation of the potential. This leads to synergy dynamics of vortices and solitons which have not been previously reported in quantum fluids.
