dc.description.abstract
Ultracold atoms and their non-equilibrium evolution present an ideal platform to study fundamental processes of quantum field theory and the relaxation dynamics of quantum many-body systems. Following a general introduction to continuous analogue quantum simulators, I will present some recent results on vortex dynamics in Bose Einstein condensates, in particular the sound-ring radiation of dense vortex clusters and the superradiant instability leading to the decay of multiply quantized vortices. For the latter, a meta-stable bound state for vortices of the same circulation is found in finite size systems. A WKB analysis captures the relevant dynamical processes, consistent with full simulations of the stochastic Gross-Pitaevskii equation.
