Normal state of highly polarized fermi gases: simple many-body approaches

We consider the problem of a single ? atom in the presence of a Fermi sea of ? atoms, in the vicinity of a Feshbach resonance. We calculate the chemical potential and the effective mass of the ? atom using two simple approaches: a many-body variational wave function and a T-matrix approximation. The...
