Abstract:

Since the early work of Kohn and Sham Density Functional Theory (DFT) in Coulombic systems has been developed as a very powerful, in principle exact, tool for the description of quantum mechanical many-body systems. In nuclear physics Density Dependent Hartree-Fock (DDHF) theory introduced in the seventies by Vautherin and Brink have turned out to provide an extremely successful non-relativistic description of nuclear ground states and excited states all over the periodic table. They are considered as density functional theories for strongly interacting nuclear systems. Since spin degrees of freedom play an extremely important role in nuclear physics a spin-orbit term has to be included in these theories which depends on additional phenomenological parameters…..In this talk we compare modern relativistic and non-relativistic functionals, in particular their limits and their successes for the description of static and dynamic properties of nuclei.
