dc.description.abstractA cranking harmonic oscillator model, widely used for the physics of fast rotating nuclei and Bose-Einstein condensates, is re-investigated in the context of -symmetry. The instability points of the model are identified as exceptional points. It is argued that - even though the Hamiltonian appears Hermitian at first glance - it actually is not Hermitian within the region of instability. © 2007 IOP Publishing Ltd.
