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…
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…
Local-spin-density functional for multideterminant density functional theory
Simone Paziani, Saverio Moroni, Paola Gori-Giorgi +1
Based on exact limits and quantum Monte Carlo simulations, we obtain, at any density and spin polarization, an accurate estimate for the energy of a modified homogeneous electron g…
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…
