IBM: parameter symmetry, hidden symmetries and transformations of boson operators
Abstract
A symmetry of the parameter space of interacting boson models IBM1 and IBM2 is studied. The symmetry is associated with linear canonical transformations of boson operators, or, equivalently, with the existence of different realizations of the symmetry algebras of the models. The relevance of the parameter symmetry to physical observables is discussed.
