On the way to a microscopic derivation of covariant density functional theory,

Abstract

Several problems encountered on the way to a microscopic derivation of covariant density functionals are discussed. The starting point are semi-microscopic functionals adjusted to ab-initio calculations in nuclear matter. Since it is impossible to derive in this way the strength of tensor terms in such functionals we propose a solution of the relativistic Brueckner- Hartree-Fock equations in finite nuclei and show first results.
