Wave-function entropy and dynamical symmetry breaking in the interacting boson model
The degree of chaos in the simplest interacting boson model (IBM-1) is compared with what we call the ``dynamical symmetry content'' of the system. The latter is represented by the information entropy of the eigenfunctions with respect to bases associated with dynamical symmetries of the IBM-1, and expresses thus the …
