Figures 6 - 9 display various trends across the periodic table, utilizing the data contained in the tables.
Fig. 6: Difference of
LDA and
LSD total energies of neutral atoms, vs. atomic number
Z.
Fig. 7: Difference of LDA and RLDA total energies of neutral atoms, vs. atomic number Z.
Fig. 8: Difference of ScRLDA and RLDA total energies of neutral atoms, vs. atomic number Z.
Fig. 9: Ionization potentials of the elements, as obtained from
experiment (blue line, to be referred to scale on left)); and differences of calculated and experimental values for the
LDA (black),
LSD (green), and
RLDA (red) approximations, all to be referenced to the right-hand energy scale.
