Abstract:

Density functional theory provides a relatively simple and universal description of the ground state properties of quantum mechanical many-body systems. We discuss here applications for atomic nuclei. In such theories the complicated many-body problem is mapped onto simple mean field calculations. Correlations are taken into account by the concept of symmetry breaking, such as for instance deformations of various types and the violation of particle numbers. Such functionals produce soliutions which are easy to visualize and relatively simple to handle. In nuclei relativistic functionals play an important role. At the moment all these functionals are determined phenomenologically by adjusting the underlying parameters to expermimental data, such ad ground state energies and radii. We also discuss first attempts to derive such functionals from ab-initio calculations, i.e. from the bare interaction between the nucleons in the framework of relativistic Brueckner-Hartree-Fock theory.
