Amplifying on a proposal by O’Dell et al. for the realization of Bose-Einstein condensates of neutral atoms with attractive 1/r interaction, we point out that the instance of self-trapping of the condensate, without an external trap potential, is physically best understood by introducing appropriate “atomic” units. This reveals a remarkable scaling property: the physics of the condensate depends only on the two parameters N2a /au and /N2, where N is the particle number, a the scattering length… CONTINUE READING
