      EXOTIC NUCLEAR STRUCTURE: COVARIANT ENERGY
            DENSITY FUNCTIONALS AND BEYOND

            Prof. dr. sc. Dario Vretenar
Department of Physics, University of Zagreb, Croatia

The framework of covariant energy density functionals has  been applied in
the description of a variety of nuclear structure phenomena, not only in
spherical and deformed nuclei along the valley of beta-stability, but also
in exotic systems with extreme isospin values and close to the particle
drip-lines. The latest advances in phenomenological density functionals,
as well as new microscopic approaches and constraints will be reviewed.
    Self-consistent covariant mean-field models  have recently been
extended to include additional correlations related to restoration of
broken symmetries and to fluctuations of the quadrupole deformation.
This approach enables a quantitative description of the evolution of
shell-structure, deformation and shape coexistence phenomena in nuclei
with soft potential energy surfaces, and singular properties of
excitation spectra and transition rates at critical points of quantum
shape phase transitions.
    The relativistic quasiparticle random-phase approximation has been
employed in studies of dynamical aspects of exotic nuclear structure.
New and interesting results include the evolution of low-lying dipole
strength in neutron-rich nuclei and the isotopic dependence of the
pygmy dipole resonance, prediction of the occurrence of pygmy dipole
resonances in proton-rich nuclei, calculations of beta-decay rates of
r-process nuclei, and modelling charged-current neutrino-nucleus
reactions.
