Query: Vortex Properties of a Resonant Superfluid   The properties of a vortex in a rotating superfluid Fermi gas are studied in
the unitary limit. A phenomenological approach based on Ginzburg-Landau theory
is developed for this purpose. The density profiles, including those of the
normal fluid and superfluid, are obtained at various temperatures and rotation
frequencies. The superfluid and normal fluid densities can be identified from
the angular momentum density. The total free energy and angular momentum of the
vortex are also obtained.
