Perturbation-induced defects in trapped superfluids exhibit generic behavior
Peter Scherpelz, Karmela Padavić, Andy Murray +3
We investigate equilibration processes shortly after sudden perturbations are applied to ultracold trapped superfluids. We show the similarity of phase imprinting and localized den…
Phase Imprinting in Equilibrating Fermi Gases: The Transience of Vortex Rings and Other Defects
Peter Scherpelz, Karmela Padavić, Adam Rançon +3
We present numerical simulations of phase imprinting experiments in ultracold trapped Fermi gases which are in good agreement with recent, independent experimental results. Our foc…
Nucleation of Spontaneous Vortices in Trapped Fermi Gases Undergoing a BCS-BEC Crossover
A. Glatz, H. L. L. Roberts, I. S. Aranson +1
We study the spontaneous formation of vortices during the superfluid condensation in a trapped fermionic gas subjected to a rapid thermal quench via evaporative cooling. Our work i…
