Explicit local exchange-correlation potentials
The possibilities of the Hohenberg-Kohn-Sham local density theory are explored in view of recent advances in the theory of the interacting electron gas. The authors discuss and provide numerical data for the effective exchange-correlation potentials μxc for ground state problems and Vxc for excitation spectra. The potential μxc(r) is written as a factor β(ρ(r)), which depends on the local density
