Abstract: 
The transition from mean-field to correlation dynamics is studied by nuclear many-body theory in nuclear matter and finite nuclei at extreme isospin. In-medium interactions in nuclear and hypernuclear matter are described by DDRH theory with density dependent meson-baryon vertex functionals. In ladder approximation, their structure is derived from Dirac-Brueckner theory. Relativistic mean-field results are presented ranging from nuclear matter over isotopic chains of nuclei to neutron stars. Dynamical correlations from pairing interactions and core polarization are found to increase strongly when approaching the driplines. This is accompanied by a strong reduction of mean-field configurations, as indeed observed in recent experiments. Anharmonicities in dipole excitations are investigated along isotopic chains including up to three phonon admixtures and using microscopic HFB quasiparticle input. The pygmy dipole resonance is found to provide a clear signature for neutron skins. (C) 2004 Elsevier B.V. All rights reserved.
