摘要: Explicit kinetic-energy density functionals for noninteracting electron systems that are based on reproducing the linear response function in homogeneous limit most accurate approximations to exact Kohn-Sham functional. In this work we study several such models one-dimensional systems. case, geometrical simplicity allows calculation of static resulting from these inhomogeneous Likewise, discussion energies and profiles obtained is easier clearer than more realistic problems. Special attention paid application explicit kinetic energy with odd noninteger number particles.
