TL;DR: In this paper, the authors employed relativistic nuclear energy density functional (RNEDF) and covariance analysis related to 2 fitting of the model parameters to identify relevant observables for dipole excita- tions, which strongly correlate with the neutron-skin thickness (rnp), symmetry energy at saturation density (J) and slope of the symmetry energy (L).

TL;DR: In this article, the authors used the AGDR excitation energy to calculate the symmetry energy at saturation and the slope of symmetry energy, which is linearly correlated with the predicted value of the neutron-skin thickness.

TL;DR: In this article, the relativistic random phase approximation is applied in the analysis of the evolution of the isovector dipole response in nuclei with a large neutron excess, and the self-consistent framework is extended to study the possible onset of low-energy collective isovectors dipole modes.

TL;DR: In this article, the relativistic Hartree-Bogoliubov (RHB) model is extended to include density-dependent meson-nucleon vertex functions.
