摘要：

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 nmuch greater thana(-3) , the energy per particle, chemical potential, and square of the sound speed are independent of the scattering length and proportional to n(2/3) , as in Fermi systems. The condensate is quenched at densities na(3)similar or equal to1 .
