Scalar two-level boson model to study the interacting boson model phase diagram in the Casten triangle. Physical Review C: Nuclear Physics, 73 (5), 054305.2469-9985 (impreso)2469-9993 (electrónico)http://hdl.handle.net/11441/64436We introduce a simple two-level boson model with the same energy surface as the Q-consistent interacting boson model Hamiltonian. The model can be diagonalized for large number of bosons and the results used to check analytical finite-size corrections to the energy gap and the order parameter in the critical region.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1103/PhysRevC.73.054305
