Abstract
We revise the Thomas-Fermi approximation for describing vortex states
in Bose condensates of magnetically trapped atoms. Our approach is
based on considering the
limit rather than the
limit as Thomas-Fermi approximation in close analogy with
the Fermi systems. Even for relatively small numbers of trapped
particles we find good agreement between Gross-Pitaevskii and
Thomas-Fermi calculations for the different contributions to the total
energy of the atoms in the condensate. We also discuss the application
of our approach to the description of vortex states in superfluid
fermionic systems in the Ginzburg-Landau regime.
