Query: Wave-function entropy and dynamical-symmetry breaking in the interacting
  boson model   The degree of chaos in the 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
localization of actual eigenfunctions in these symmetry bases. The
wave-function entropy is shown to be a sensitive tool for monitoring the
processes of a single dynamical-symmetry breaking or transitions between two
and more symmetries. For the IBM-1 hamiltonians studied here, the known
features related to chaos, namely the dependence of chaotic measures on the
hamiltonian parameters (position in the Casten triangle) and on the angular
momentum, turn out to be correlated with the behaviour of the wave-function
entropy. PACs 21.60.Fw; 05.45.+b
