## Abstract The aim of this note is to ascertain the importance of the Fermi–Amaldi (FA) correction for the Thomas–Fermi (TF) theory of atoms. For this purpose, an analytic trial electron density has been chosen and the Thomas–Fermi–Amaldi (TFA) energy expression has been minimized by the Ritz meth

By using entropy inequalities with coherent states we prove that for atoms and molecules the partition function of Thomas-Fermi theory becomes exact in the limit Z+ co, in the appropriate scaling. Furthermore the Gibbs state over a suitable algebra converges to a pure state over classical densities

In the application of the optimized Thomas-Fermi theory to condensed phase systems, it has proved convenient to introduce a sum of atom-centered functions to represent the most rapidly varying part of the electron density near the nuclei. By extraction of this portion of the density, attention can b
