The electron–electron repulsion energy as a functional of the Hartree–Fock one-electron density matrix

Autor: Roberto Lopez-Boada, Jerzy Cioslowski

Publikováno v: Chemical Physics Letters. 307:445-452

The recently proposed expression that yields approximate electron–electron repulsion energy as a functional V ee [ Γ HF ] of the Hartree–Fock one-electron reduced density matrix Γ HF is studied in detail. A scaling property of the screening fun

Approximate one-electron density matrix functionals for the electron–electron repulsion energy from the hypervirial theorem

Autor: Jerzy Cioslowski, Roberto Lopez-Boada

Publikováno v: The Journal of Chemical Physics. 109:4156-4163

Application of the hypervirial theorem to a certain class of two-electron operators yields the electron–electron repulsion energy as an approximate functional of the Hartree–Fock one-electron reduced density matrix. This functional is entirely pa

Properties of electron density and other one-electron observables derived from generalized Hiller–Sucher–Feinberg identities

Autor: Jerzy Cioslowski, Roberto Lopez-Boada

Publikováno v: The Journal of Chemical Physics. 109:1230-1237

A generalization of the Hiller–Sucher–Feinberg (HSF) and Rassolov–Chipman identities for the electron density is presented. A companion expression for the electrostatic potential is derived. Properties of the electron density furnished by the g
