Basis Representation for Nuclear Densities from Principal Component Analysis
Chen-Jun Lv, Tian-Yu Wu, Xin-Hui Wu +2
We develop an efficient method to represent nuclear densities using basis functions extracted via Principal Component Analysis (PCA). Applying PCA to densities of 75 nuclei calcula…

Equation of state of spin-polarized nuclear matter in the relativistic Hartree-Fock method
Toi Tachibana, Kouichi Hagino, Kenichi Yoshida +1
We calculate the equation of state (EOS) of spin-polarized nuclear matter in the relativistic Hartree-Fock method. To this end, we employ the relativistic point-coupling model, wit…
