    "abstract": "We demonstrate analytically that a Bose-Einstein condensate confined in a\nharmonic trap with zero-range attractive interparticle interactions is unstable\nif there is more than 1 boson. Replacing the zero-range interaction by a\nshort-range attractive interaction lifts the instability, and leads to a\npronounced clustering, by which the particles leak out of the condensate.",
