Investigation of nuclear structure using nuclear energy density functional theory.Nuclear energy density functional (NEDF) theory maps the nuclear many-body problem onto a one-body problem that depends on the ground state densities and currents of the nucleons. The NEDF theory is implemented in terms of self-consistent mean-field approaches, and can provide accurate descriptions of nuclei – ranging from light to superheavy – with comparably low computational cost.
To investigate open-shell nuclei, NEDF theory is extended to account for pairing correlations which led to the formulation of the relativistic Hartree-Bogoliubov model, and I will be using this model to study ground-state properties of nuclei at both zero and finite temperatures.
Traditionally the nucleus is viewed as spherical, but this is not always the case, and I have particular interest in exotic nuclear structures that are often found near to the drip lines. I will extend my investigations to include excited states of deformed nuclei – which give rise to a further plethora of exotic structures and properties – and also how temperature influences these properties.
