Abstract
|
|
|
|
| Determination of the kinetic energy functional is one of the central problems in the density functional theory of a many-fermion system. We consider several many-fermion systems to be characterized by simple confining potentials: the harmonic oscillator potential in one and three dimensions, the Coulomb potential, and the potential V(x) = -U(o)sech(2)(x/L). We discuss for each of these cases the differential equation that determines the fermion density in the given potential, and the corresponding kinetic energy density.
