We present a theoretical interpretation of a recent experiment presented by Zwierlein et al. [Nature (London) 442, 54 (2006)] on the density profile of Fermi gases with unbalanced spin populations. We show that in the regime of strong interaction, the boundaries of the three phases observed by Zwierlein et al. can be characterized by two dimensionless numbers {eta}{sub {alpha}} and {eta}{sub {beta}}. Using a combination of a variational treatment and a study of the experimental results, we infer rather precise bounds for these two parameters.

Theory of ultracold atomic Fermi gases (2007, methodology): “The same value of A has been obtained from an exact diagrammatic Monte Carlo calculation (Prokof’ev and Svistunov, 2007) and, quite remarkably, also employing a simple variational approach based on a single particle-hole wavefunction (Chevy, 2006b, Combescot et al., 2007).”
