Ground State Properties of Fermi Gases in the Strongly Interacting Regime
The ground state energies and pairing gaps in dilute superfluid Fermi gases
have now been calculated with the quantum Monte Carlo method without detailed
knowledge of their wave functions. However, such knowledge is essential to
predict other properties of these gases such as density matrices and pair
distribution functions. We present a new and simple method to optimize the wave
functions of quantum fluids using Green's function Monte Carlo method. It is
used to calculate the pair distribution functions and potential energies of
Fermi gases over the entire regime from atomic Bardeen-Cooper-Schrieffer
superfluid to molecular Bose-Einstein condensation, spanned as the interaction
strength is varied.Comment: 4 pages, 4 figure
