Atomic Physics 2020-05-22 v2 Chemical Physics

Abstract

A general penalty method is presented for the construction of of Kohn-Sham system for given density through Levy's constrained-search. The method uses a functional S[ρ]S[\rho] of one's choice. Different forms of S[ρ]S[\rho] are employed to calculate the kinetic energy and exchange-correlation potential of atoms, jellium spheres, and Hookium and consistency among results obtained from them is shown.
