Nuclear energy density functionals from empirical ground-state densities

  title={Nuclear energy density functionals from empirical ground-state densities},
  author={Giacomo Accorto and Tomoya Naito and Haozhao Liang and T. Niksic and Dario Vretenar},
A model is developed, based on the density functional perturbation theory and the inverse KohnSham method, that can be used to improve relativistic nuclear energy density functionals towards an exact but unknown Kohn-Sham exchange-correlation functional. The improved functional is determined by empirical exact ground-state densities of finite systems. A test of the model and an illustrative calculation are performed, starting from two different approximate functionals, to reproduce the…

Effects of finite-light-speed correction for the Coulomb interaction on nuclear binding energies and radii in spherical nuclei
The finite-light-speed correction to the Coulomb interaction called the Breit correction is discussed with Skyrme Hartree-Fock calculations. It is found that the correction to the total energy is

Exact exchange-correlation potentials from ground-state electron densities
This work presents a numerically robust and accurate scheme to evaluate the exact exchange-correlation potentials from correlated ab-initio densities, and proposes an approach for an accurate solution to the inverse DFT problem.
Turning the nuclear energy density functional method into a proper effective field theory: reflections
Nuclear energy density functionals (EDFs) have a long history of success in reproducing properties of nuclei across the table of the nuclides. They capture quantitatively the emergent features of
REVIEW ARTICLE: The relativistic mean-field description of nuclei and nuclear dynamics
The relativistic mean-field model of the nucleus is reviewed. It describes the nucleus as a system of Dirac nucleons which interact in a relativistic covariant manner via meson fields. The meson
