Relativistic nuclear energy density functionals: Mean-field and beyond

Nuclear Energy Density Functionals Constrained by Low-Energy QCD

A microscopic framework of nuclear energy density functionals is reviewed, which establishes a direct relation between low-energy QCD and nuclear structure, synthesizing effective field theory methods and principles of density functional theory. Guided by two closely related features of QCD in the lowenergy limit: a) in-medium changes of vacuum condensates, and b) spontaneous breaking of chiral...

Rpa Correlations and Nuclear Densities in Relativistic Mean Field Approach

Abstract. The relativistic mean field approach (RMF) is well known for describing accurately binding energies and nucleon distributions in atomic nuclei throughout the nuclear chart. The random phase approximation (RPA) built on top of the RMF is also a good framework for the study of nuclear excitations. Here, we examine the consequences of long range correlations brought about by the RPA on t...

A microscopic estimate of the nuclear matter compressibility and symmetry energy in relativistic mean-field models

The relativistic mean-field plus RPA calculations, based on effective Lagrangians with densitydependent meson-nucleon vertex functions, are employed in a microscopic analysis of the nuclear matter compressibility and symmetry energy. We compute the isoscalar monopole and the isovector dipole response of Pb, as well as the differences between the neutron and proton radii for Pb and several Sn is...

K-Nuclear Bound States in Relativistic Mean-Field Theory

We have developed the relativistic mean field model to the study of kaonic nuclei. Starting with the Lagrangian for nucleons and (anti)kaon meson, the equations of motion for nucleon field, scalar meson, vector meson and (anti)kaon meson fields are deduced. By self-consistently solving the equations of motion, the K−-nuclear deeply bound states are obtained for the nuclei with A ≥ 8. The K−-nuc...
