The correlation energy as an explicit functional of the one-particle density matrix from a determinantal reference state
James Finley
Using an approach based on many body perturbation theory, the correlation energy $\cEco$ is expressed as an explicit functional of , , and , where is the one-par…
State-Specific Kohn-Sham Density Functional Theory
James P. Finley
A generalization of the Kohn--Sham approach is derived where the correlation-energy functional depends on the one-particle density matrix of noninteracting states and on the extern…
The conversion of nonlocal one-body operators into local ones: The Slater potential revisited
James P. Finley
One-particle Schrodinger equations are considered, e.g., the Hartree--Fock equations, that contain a nonlocal operator, e.g., the Hartree--Fock exchange operator, where this operat…
Developments for Reference--State One--Particle Density--Matrix Theory
James P. Finley
Brueckner orbitals, and the density of the Brueckner reference-state, are shown to satify the same cusp condition -- involving the nuclear charges -- as natural- and Hartree--Fock-…
