The model includes harmonic, two-body and three-body interactions. Using the underlying conformal SU(1,1) algebra, we find the exact eigenenergies corresponding to a class of the exact global collective states. Analysing corresponding Fock space, we detect the universal critical point at which the model exhibits singular behaviour.7 pages, presented at XIII International Colloquium "Integrable Systems and Quantum Groups", June 17-19 2004.,PragueHigh Energy Physics - Theorytext
