Abstract:
Among the microscopic approaches to the nuclear many-body problem, energy density functionals (EDF) provide the most complete and accurate description of ground states and collective excitations over the whole nuclide chart. The current generation of relativistic EDFs, using parameters adjusted to reproduce empirical properties of nuclear matter and bulk properties of finite nuclei, has been applied to studies of arbitrarily heavy nuclei, exotic nuclei far from beta-stability, and systems at the nucleon drip-lines. In addition to recent advances, future hallenges for nuclear EDFs will be reviewed. Arguably one of the most important is a fully microscopic foundation based on the underlying theory of strong interactions. When considering applications, equally important is to develop EDF-based tructure models that go beyond the static mean-field approximation. Detailed predictions of excitation spectra and transition rates necessitate the inclusion of correlations related to the restoration of broken symmetries and to fluctuations of collective variables.

Abstract:
Atomic nuclei are stable only in a relatively narrow range of neutron and proton numbers. Light systems are dominated by symmetric combinations.For heavier nuclei an increasing neutron excess is observed and the stability seems to be limited for large proton numbers. The origin of this stability and its limitations are discussed on the basis of simple principles of quantum mechanics and relativity and the properties of nuclear forces. Modern accelerators with radioactive beams allow the study of rare isotopes and such investigations are presently at the forefront of nuclear science all over the world. Many of these nuclei play an important role in astrophysical processes. Their properties decide upon the origin and the distribution of elements in the universe and on earth. Nuclear density functional theory provides an important tool for a theoretical description of these systems and for our understanding of the nuclear many-body problem in general.
