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.10 pages, 2 PS-figuresCondensed MatterExactly Solvable and Integrable SystemsAtomic Physicstext
