Description
Nuclear structure models built from phenomenological mean fields, the effective nucleonnucleon interactions (or Lagrangians), and the realistic bare nucleon-nucleon interactions are
reviewed. The success of covariant density functional theory, which starts from effective
Lagrangians, to describe nuclear ground-state and excited-state properties and its influence on
Brueckner theory within the relativistic framework are focused upon. The challenges and
ambiguities of predictions for unstable nuclei without data or for high-density nuclear matter,
arising from covariant density functionals, are discussed. The basic ideas in building an ab initio
covariant density functional for nuclear structure from ab initio calculations with realistic
nucleon-nucleon interactions for both nuclear matter and finite nuclei are presented. The current
status of fully self-consistent relativistic Brueckner-Hartree-Fock (RBHF) calculations for finite
nuclei or neutron drops (ideal systems composed of a finite number of neutrons and confined
within an external field) is reviewed. The guidance and perspectives towards an ab initio covariant
density functional for nuclear structure derived from the RBHF results are provided.
