Universal solutions for interacting bosons in one-dimensional harmonic traps
arXiv:cond-mat/0108474 · doi:10.1103/PhysRevA.65.033606
Abstract
We consider systems of interacting bosons confined to one-dimensional harmonic traps. In the limit of perturbatively weak two-body interactions the system exhibits several universal states that are exact solutions for a large class of two-body interactions. These states are closely related to the exact solutions found previously in rotating Bose-Einstein condensates.
