Abstract:
I will present results on wave-vortex interaction emerging from an expanding compact vortex cluster in a two- dimensional Bose-Einstein condensate. Adapting techniques developed for compact gravitational objects I present the characteristic modes of the wave-vortex interaction perturbatively around an effective vortex flow field. This demonstrates the existence of orbits or sound-rings, in analogy to gravitational light-rings, and enables to compute the characteristic spectrum for the out-of-equilibrium vortex cluster.
