Abstract

This project aims to study vortices and turbulence in ultracold atomic gases in the quantum regime. Among the interesting effects being investigated is the quantum turbulence in a non-kinetically dominated regime, but with strong interactions. We intend to combine numerical methods and experiments to study various aspects of Bose-Einstein condensates: the dynamics and distribution of vortices, presence of impurities and to relate the occurrence of Faraday density waves and quantum turbulence. We propose quantum Monte Carlo methods to obtain accurate results in strongly interacting vortices, and we will explore the duality between Fermi gases and neutron matter to connect experiments with ultracold atoms and nuclear physics. The background of the candidate and the supervisor, the resources of the host institution, and the network of collaborators, will contribute to the development of the project.
