From Planar Solitons to Vortex Rings and Lines: Cascade of Solitonic Excitations in a Superfluid Fermi Gas

Mark J. H. Ku, Biswaroop Mukherjee, Tarik Yefsah +1

We follow the time evolution of a superfluid Fermi gas of resonantly interacting ${}^6$Li atoms after a phase imprint. Via tomographic imaging, we observe the formation of a planar d…
