RT Journal Article T1 A scalar two-level boson model to study the IBM phase diagram in the Casten triangle A1 Vidal, Julien A1 Arias Carrasco, José Miguel A1 Dukelsky, J. A1 García Ramos, José Enrique K1 Bosones AB We introduce a simple two-level boson model with the same energy surface as the Q-consistentInteracting Boson Model Hamiltonian. The model can be diagonalized for large number of bosonsand the results used to check analytical finite-size corrections to the energy gap and the orderparameter in the critical region.
