Adiabatic-connection fluctuation-dissipation density-functional theory based on range separation
Julien Toulouse, Iann C. Gerber, Georg Jansen +2
An adiabatic-connection fluctuation-dissipation theorem approach based on a range separation of electron-electron interactions is proposed. It involves a rigorous combination of sh…
Degeneracy and size consistency in electronic density functional theory
Paola Gori-Giorgi, Andreas Savin
The electronic structure calculations based upon energy density functionals are highly successful and widely used both in solid state physics and quantum chemistry. Moreover, the H…
Strictly correlated electrons in density functional theory: A general formulation with applications to spherical densities
Michael Seidl, Paola Gori-Giorgi, Andreas Savin
We reformulate the strong-interaction limit of electronic density functional theory in terms of a classical problem with a degenerate minimum. This allows us to clarify many aspect…
Short-range exchange-correlation energy of a uniform electron gas with modified electron-electron interaction
Julien Toulouse, Andreas Savin, Heinz-Jürgen Flad
We calculate the short-range exchange-correlation energy of the uniform electron gas with two modified electron-electron interactions. While the short-range exchange functionals ar…
Kohn-Sham calculations combined with an average pair-density functional theory
Paola Gori-Giorgi, Andreas Savin
A recently developed formalism in which Kohn-Sham calculations are combined with an ``average pair density functional theory'' is reviewed, and some new properties of the effective…
Model hamiltonians in density functional theory
Paola Gori-Giorgi, Julien Toulouse, Andreas Savin
The formalism of Kohn and Sham uses a specific (model) hamiltonian which highly simplifies the many-electron problem to that of noninteracting fermions. The theorem of Hohenberg an…
Properties of short-range and long-range correlation energy density functionals from electron-electron coalescence
Paola Gori-Giorgi, Andreas Savin
The combination of density functional theory with other approaches to the many-electron problem through the separation of the electron-electron interaction into a short-range and a…
Van der Waals forces in density functional theory: perturbational long-range electron interaction corrections
Janos G. Angyan, Iann C. Gerber, Andreas Savin +1
Long-range exchange and correlation effects, responsible for the failure of currently used approximate density functionals in describing van der Waals forces, are taken into accoun…
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…
