Self-Consistent Harmonic Oscillator Model and Tilted Rotation
W. D. Heiss, R. G. Nazmitdinov
The three dimensional harmonic oscillator model including a cranking term is used for an energy variational calculation. Energy minima are found under variation of the three oscill…
Electronic shell structure of large metallic clusters in the modified harmonic oscillator
W. D. Heiss, R. G. Nazmitdinov
Shell structure in the single particle spectrum of deformed harmonic oscillator potentials when a term proportional to is added is analyzed for a large particle number…
Quantum Chaos, Degeneracies and Exceptional Points
W. Dieter Heiss, Stefanel Radu
It is argued that, if a regular Hamiltonian is perturbed by a term that produces chaos, the onset of chaos is shifted towards larger values of the perturbation parameter if the unp…
Periodic Orbits and Shell Structure in Octupole Deformed Potentials
W. Dieter Heiss, Rashid G. Nazmitdinov, Stefanel Radu
The effect of an octupole term in a quadrupole deformed single particle potential is studied from the classical and quantum mechanical view point. Whereas the problem is nonintegra…
Chaos in Axially Symmetric Potentials with Octupole Deformation
W. Dieter Heiss, Rashid G. Nazmitdinov, Stefanel Radu
Classical and quantum mechanical results are reported for the single particle motion in a harmonic oscillator potential which is characterized by a quadrupole deformation and an ad…
