Phys. Rev. Lett. 64, 1479–1482 (1990)Dynamical quasidegeneracies and separation of regular and irregular quantum levelsSee Also: Erratum Received 4 August 1989; published in the issue dated 26 March 1990 Dynamical quasidegeneracies may arise in the spectrum of systems having discrete symmetries. They are semiclassically interpreted as quantized congruent but distinct tori in phase space. With them the separation of regular and irregular states in the quantum spectrum of some mixed phase-space systems may be performed in a simple yet clear fashion. At finite energies (h finite), the frontier between regular and irregular states is not sharp. This is illustrated by the study of two coupled quartic oscillators. © 1990 The American Physical Society URL:
