“…The disappearance of gray soliton and phonon excitations was demonstrated in [27] by oscillating a repulsive obstacle in a quasi-1D trapped BEC at high obstacle velocities. It was found in [28] that vibration of an obstacle modulates the vortex street, theoretically predicted in [10], breaking a symmetry.…”

We investigate by numerical simulations the pattern formation after an oscillating attractiverepulsive obstacle inserted into the flow of a Bose-Einstein condensate. For slow oscillations we observe a complex emission of vortex dipoles. For moderate oscillations organized lined up vortex dipoles are emitted. For high frequencies no dipoles are observed but only lined up dark fragments. The results shows that the drag force turns negative for sufficiently high frequency. We also successfully model the ship waves in front of the obstacle. In the limit of very fast oscillations all the excitations of the system tend to vanish.PACS numbers: 03.75.
