Study of Some Simple Approximations to the Non-Interacting Kinetic Energy Functional

Within the framework of density functional theory, a study of approximations to the enhancement factor of the non-interacting kinetic energy functional Ts[ρ] has been presented. For this purpose, the model of Liu and Parr (Liu and Parr, Phys Rev A 1997, 55, 1792) based on a series expansion of Ts[ρ]...
