      Finite-size scaling exponents in the interacting boson model 

      Dusuel, Sébastien; Vidal, Julien; Arias Carrasco, José Miguel; Dukelsky, Jorge; García Ramos, José Enrique (American Physical Society, 2005-07-01)
      We investigate the finite-size scaling exponents for the critical point at the shape-phase transition from U(5) (spherical) ...
