Generic equilibration dynamics of planar defects in trapped atomic superfluids
Generic equilibration dynamics of planar defects in trapped atomic superfluids
We investigate equilibration processes shortly after sudden perturbations are applied to ultracold trapped superfluids. We show the similarity of phase imprinting and localized density depletion perturbations, both of which initially are found to produce "phase walls". These planar defects are associated with a sharp gradient in the phase. Importantly they …
