Periodic-orbit bifurcations as the origin of nuclear deformations
نویسنده
چکیده
Semiclassical analysis of shell structures in realistic nuclear potentials are presented using periodicorbit theory. We adopted r potential model and examined classical-quantum correspondence using Fourier transformation technique. Spin-orbit coupling is also taken into account in the model Hamiltonian. Gross shell structure for a certain combination of surface diffuseness and spin-orbit parameters are investigated and its relation to pseudospin symmetry is discussed. Analysis of superdeformed shell structure in realistic model is also presented.

Relationship between quantum shell structure and classical periodic orbits is briefly reviewed on the basis of semi-classical trace formula. Using the spheroidal cavity model, it is shown that threedimensional periodic orbits, which are born out of bifurcation of planar orbits at large prolate deformations, generate the superdeformed shell structure. Introduction Existence of superdeformed (SD)...
متن کاملGlobal analysis of periodic orbit bifurcations in coupled Morse oscillator systems: time-reversal symmetry, permutational representations and codimension-2 collisions.
In this paper we study periodic orbit bifurcation sequences in a system of two coupled Morse oscillators. Time-reversal symmetry is exploited to determine periodic orbits by iteration of symmetry lines. The permutational representation of Tsuchiya and Jaffe is employed to analyze periodic orbit configurations on the symmetry lines. Local pruning rules are formulated, and a global analysis of po...
متن کاملSemiclassical Analysis of the Supershell Effect in Reflection - Asymmetric Superdeformed Oscillator
An oscillatory pattern in the smoothed quantum spectrum, which is unique for single-particle motions in a reflection-asymmetric superdeformed oscillator potential, is investigated by means of the semiclassical theory of shell structure. Clear correspondence between the oscillating components of the smoothed level density and the classical periodic orbits is found. It is shown that an interferen...
متن کاملKUNS 1285 Periodic Orbits and New Shell Structure Generated by a Combination of Quadrupole and Octupole Deformations
In this talk, we would like to present a simple model in which a prominent shell structure emerges for a combination of quadrupole and octupole deformations. We shall then discuss the origin of such a new shell structure in terms of the periodic orbits and their bifurcations. Importance of shell effects for the occurrence of reflection-asymmetric deformed shapes have been lively discussed in va...
متن کاملPeriodic orbits in tall laterally heated rectangular cavities.
This study elucidates the origin of the multiplicity of stable oscillatory flows detected by time integration in tall rectangular cavities heated from the side. By using continuation techniques for periodic orbits, it is shown that initially unstable branches, arising at Hopf bifurcations of the basic steady flow, become stable after crossing Neimark-Sacker points. There are no saddle-node or p...
