Abstract
Nuclear matter and finite nuclei at extreme isospin are studied using the DDRH field theory. A relativistic energy density functional with density dependent meson–baryon vertex functionals, derived from the Dirac–Brueckner theory, is derived. Dynamical correlations from pairing interactions and core polarization are found to increase strongly when approaching the driplines. The above particle threshold core polarization gives rise to narrow Fano Resonances as a new mode of continuum excitation. This is accompanied by a strong reduction of mean-field configurations. Pygmy dipole resonances are found to provide a clear signature for neutron skins.
