Abstract
We show that in the search of a unified mean field description of finite nuclei and of nuclear and neutron matter even at high densities, the relativistic nuclear model derived from effective field theory and density functional theory methods constitutes a competitive framework. The model predicts a soft equation of state, owing to the additional meson interaction terms, consistently with the results of the microscopic Dirac-Brueckner-Hartree-Fock theory and recent experimental observations from heavy ion collisions. In finite systems, after inclusion of the pairing correlations, the model is able to describe both stable and exotic nuclei. We address two examples at the limits of the nuclear landscape. On the one hand, we analyze the giant halo effect and the isoscalar giant monopole resonance in very neutron-rich Zr isotopes. On the other hand, we discuss the structure of superheavy nuclei with double shell closures.
