Simple model for the spherically- and system-averaged pair density: Results for two-electron atoms
Paola Gori-Giorgi, Andreas Savin
As shown by Overhauser and others, accurate pair densities for the uniform electron gas may be found by solving a two-electron scattering problem with an effective screened electro…
Short-range exchange and correlation energy density functionals: beyond the local density approximation
Julien Toulouse, Francois Colonna, Andreas Savin
We propose approximations which go beyond the local density approximation for the short-range exchange and correlation density functionals appearing in a multi-determinantal extens…
Long-range/short-range separation of the electron-electron interaction in density functional theory
Julien Toulouse, Francois Colonna, Andreas Savin
By splitting the Coulomb interaction into long-range and short-range components, we decompose the energy of a quantum electronic system into long-range and short-range contribution…
