Abstract

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 densities, n>>a-3, the energy per particle, chemical potential, and square of the sound speed are independent of the scattering length and proportional to n2/3, as in Fermi systems.
