Highly polarized mixtures of atomic Fermi gases constitute a novel Fermi liquid. We demonstrate how information on thermodynamic properties may be used to calculate quasiparticle scatteringâ€¦ (More)

We calculate the energy and condensate fraction for a dense system of bosons interacting through an attractive short range interaction with positive s-wave scattering length a. At high densitiesâ€¦ (More)

We show that, within mean-field theory, the density profile of a rapidly rotating harmonically trapped Bose-Einstein condensate is of the Thomas-Fermi form as long as the number of vortices is muchâ€¦ (More)

Recent calculations indicate that in the outer parts of neutron stars nuclei are rodlike or slab-like, rather than roughly spherical. We consider the elastic properties of these phases, and argueâ€¦ (More)

Using arguments based on sum rules, we derive a general result for the average shifts of rf lines in Fermi gases in terms of interatomic interaction strengths and two-particle correlation functions.â€¦ (More)

We calculate the shift, due to interatomic interactions, of an optical transition in an atomic Fermi gas trapped in an optical lattice, as in recent experiments of Campbell et al. [Science 324, 360â€¦ (More)

We calculate energy levels of two and three bosons trapped in a harmonic oscillator potential with oscillator length a(osc). The atoms are assumed to interact through a short-range potential with aâ€¦ (More)

We consider the effect of interactions on the line shape of the two-photon 1sâˆ’2s transition in a (doubly) spin-polarized atomic hydrogen gas in terms of the interatomic interaction potentials. Weâ€¦ (More)

We show that puzzling recent experimental results on spin diffusion in a strongly interacting atomic gas may be understood in terms of the predicted spin diffusion coefficient for a generic stronglyâ€¦ (More)
