Physical Review A. Vol. 83, n. 6 (2011). DOI: 10.1103/PhysRevA.83.0621251050-2947http://hdl.handle.net/10272/5503Analytical results beyond the mean-field-limit approximation for several observables of the two-dimensional limit of the vibron model are presented. Finite-size scaling exponent values are also analytically derived. The computed corrections and scaling exponents are compared to numerical calculations for this algebraic model, based on a bosonic u(3) spectrum-generating algebra, obtaining good agreement.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/BosonesQuantum phase transitionsInteracting Boson Modeljournal article10.1103/PhysRevA.83.062125open access
