Abstract
We note the similarity between BEC (Bose-Einstein Condensates) formed of atoms between which we have long-range attraction (and shorter-range repulsions) and the field theoretic ”Q balls”. This allows us in particular to address the stability of various putative particle physics Q balls made of non-relativistic bosons (K0’s, B0’s and D0’s) using variational methods of the many-body NRS equation.
