Analytic descriptions for transitional nuclei near the critical point
نویسنده
چکیده
Exact solutions of the Bohr Hamiltonian with a five-dimensional square well potential, in isolation or coupled to a fermion by the five-dimensional spin-orbit interaction, are considered as examples of a new class of dynamical symmetry or Bose-Fermi dynamical symmetry. The solutions provide baselines for experimental studies of even-even [E(5)] and odd-mass [E(5|4)] nuclei near the critical point of the spherical to deformed γ-unstable phase transition. PACS: 21.60.Ev, 21.10.Re, 21.60.Fw

Symmetries at and Near Critical Points of Quantum Phase Transitions in Nuclei
We examine several types of symmetries which are relevant to quantum phase transitions in nuclei. These include: critical-point, quasidynamical, and partial dynamical symmetries. Symmetry plays a profound role in thermal and quantum phase transitions (QPT). The latter occur at zero temperature as a function of a coupling constant in the Hamiltonian. Such ground-state energy phase transitions ar...
متن کاملCritical-Point Structure in Finite Nuclei
Phase transitions associated with a change of shape are known to occur in dynamical systems such as nuclei. Recently, it has been recognized that such quantum shape-phase transitions are amenable to analytic descriptions at the critical points [1, 2]. For nuclei these analytic benchmarks of criticality were obtained in the geometric framework of a Bohr Hamiltonian for macroscopic quadrupole sha...

Structure of collective modes in transitional and deformed nuclei Mark Anthony Caprio 2003 The collective structure of atomic nuclei intermediate between spherical and quadrupole deformed structure presents challenges to theoretical understanding. However, models have recently been proposed in terms of potentials which are largely independent of the quadrupole deformation β [beta]. These models...

متن کامل2 8 Ju l 2 00 8 Complementary descriptions of shape / phase transitions in atomic nuclei
Shape/phase transitions in atomic nuclei have first been discovered in the framework of the Interacting Boson Approximation (IBA) model. Critical point symmetries appropriate for nuclei at the transition points have been introduced as special solutions of the Bohr Hamiltonian, stirring the introduction of additional new solutions describing wide ranges of nuclei. The complementarity of the IBA ...
