Is the ground state energy of a Bose condensate a function of the scattering length only? — •Christoph Weiss — Carl-von-Ossietzky-Universität, Fachbereich Physik, 26129 Oldenburg

It is generally believed that the ground state energy of a translationally invariant Bose condensate is a function of the scattering length only. This topic is reinvestigated both for Bose gases interacting via weak potentials and for Bose gases interacting via hard core potentials.
