Session 4: Shapes and shape-related structures of nuclei
- Peter Ring (TU Munich, Garching, Germany)
Octupole deformation, an exotic nuclear deformation that breaks reflection symmetry, is a recurrent theme of interest in nuclear structure physics. This presentation highlights recent studies on the signatures of octupole correlations and related collective excitations using the interacting boson model that is based on the nuclear density functional theory. By mapping the self-consistent...
With the construction and operation of next-generation large-scale radioactive nuclear beam facilities worldwide, numerous novel phenomena have been discovered through the excitation and decay of unstable exotic atomic nuclei, such as shape coexistence, shape phase transitions, octupole deformation, and more. These findings have brought about a fresh understanding of nuclear physics and posed...
The phenomenon of quantum phase transitions (QPTs) is highly investigated in many fields on physics, and, in particular, nuclear structure. QPTs in atomic nuclei refer to (mostly) abrupt changes in the structure of the spectrum. The changes are identified in the nuclear shapes of the ground state, with varying nucleon number - from one shape evolving to another (Type I QPT) or when another...
A central motivation for the program of ultra-relativistic nuclear collisions is to access bulk properties of QCD matter that emerge in conditions similar to those found in the early Universe or in extreme astrophysical objects. A prime example is the quark-gluon plasma (QGP), the hot phase of QCD matter that behaves like a near-perfect fluid. The spatio-temporal evolution of the QGP can be...
The nucleus is described as a system of fermions interacting via the exchange of different mesons in covariant density functional theory (CDFT). It is very successful in the description of many nuclear phenomena [1]. However, at present the absolute majority of covariant energy density functionals (CEDFs) are fitted to only spherical nuclei. This does not allow to improve the global...
