THE Q-DEFORMED MOSZKOWSKI MODEL - RPA MODES (VOL 26, PG 895, 1993)

The behaviour of the Moszkowski model within the context of quantum al gebras is studied. The Moszkowski Hamiltonian is exactly diagonalized for various values of the deformation parameter of the involved quantu m algebra. The phase transition from a vibrational regime to a rotatio nal regime is discussed in terms of the q-deformation. A coherent stat e for the ground state is introduced, and the Hartree-Fock energy and the RPA frequencies are compared with the exact values. The meaning of the q-deformation in this model is discussed.
