Microscopic Structure of a Vortex Line in a Dilute Superfluid Fermi Gas



N Nygaard, G M. Bruun, Charles W. Clark, D L. Feder


The microscopic properties of a single vortex in a dilute superfluid Fermi gas at zero temperature are examined within the framework of self-consistent Bogoliubov-de Gennes theory. Using only physical parameters as inputwe study the pair potential, the density, the energy, and the current distribution. Comparison of the numerical results with analytical expressions clearly indicates that the energy of the vortex is governed by the zero-temperature BCS coherence length.
