Summary
Two topics of current interest strongly anharmonic collective vibrations and collective rotation about a tilted axis - have been related through a theorem proposed by the principal in Theorem, states that if a system has an axis of rotational symmetry in a static mean-field approximation, then self-consistent cranking about this axis gives rise to symmetry-breaking bifurcations that occur for critical cranking frequencies Ω{sub c} given by Ω{sub c} = ω{sub μ}/K{sub μ}, where ω{sub μ} is the small-oscillation (RPA) frequency of any normal mode carrying ℏK{sub μ} (≠ 0) units of angular momentum along the symmetry axis. The bifurcations represent families of anharmonic oscillations built on the axially symmetric mean field. For certain values of K{sub μ}, the solutions appear as rotations about an axis that is tilted with respect to the principal axis of the density distribution. The theorem has been tested on some simple models in preparation for more realistic calculations that are planned for the near future.
