Covariant Density Functional Theory and Beyond for Deformed Nuclei

摘要

Density functional theory (DFT) provides a very successful description of nuclear structure in medium heavy and heavy nuclei. Covariant versions (CDFT) take into account full Lorentz invariance, a basic symmetry of QCD. It puts stringent restrictions on the number of parameters without loosing the good agreement with experimental data. The concept of DFT is a mapping of the complicated quantum mechanical many-body problem to a one-body problem, which can be solved relatively easily.
