  • Density-Functional Theory for Strongly Interacting Electrons 

    Gori-Giorgi, Paola; Seidl, Michael; Vignale, Giovanni, 1957- (American Physical Society, 2009)
    We present an alternative to the Kohn-Sham formulation of density-functional theory for the ground-state properties of strongly interacting electronic systems. The idea is to start from the limit of zero kinetic energy and ...

  • Electronic zero-point oscillations in the strong-interaction limit of density functional theory 

    Gori-Giorgi, Paola; Vignale, Giovanni, 1957-; Seidl, Michael (arXiv, 2008)
    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 operator when, in the many- electron hamiltonian, ...
