Electronic zero-point oscillations in the strong-interaction limit of density functional theory
Paola Gori-Giorgi, Giovanni Vignale, Michael Seidl
The exchange-correlation energy in Kohn-Sham density functional theory can be expressed exactly in terms of the change in the expectation of the electron-electron repulsion operato…

The high-density limit of two-electron systems: Results from the extended Overhauser approach
Paola Gori-Giorgi, Andreas Savin
The ``extended Overhauser model'' [Overhauser, Can. J. Phys. 1995, 73, 683] for the calculation of the spherically and system-averaged pair density (APD) has been recently combined…

A short-range correlation energy density functional with multi-determinantal reference
Julien Toulouse, Paola Gori-Giorgi, Andreas Savin
We introduce a short-range correlation density functional defined with respect to a multi-determinantal reference which is meant to be used in a multi-determinantal extension of th…
