Testing one-body density functionals on a solvable model
Carlos L. Benavides-Riveros, Joseph C. Várilly
There are several physically motivated density matrix functionals in the literature, built from the knowledge of the natural orbitals and the occupation numbers of the one-body red…
The lowest excited configuration of harmonium
Carlos L. Benavides-Riveros, José M. Gracia-Bondía, Joseph C. Várilly
The harmonium model has long been regarded as an exactly solvable laboratory bench for quantum chemistry [Heisenberg, 1926]. For studying correlation energy, only the ground state…
Exact phase space functional for two-body systems
José M. Gracia-Bondía, Joseph C. Várilly
The determination of the two-body density functional from its one-body density is achieved for Moshinsky's harmonium model, using a phase-space formulation, thereby resolving its p…
Density functional theory on phase space
Philippe Blanchard, José M. Gracia-Bondía, Joseph C. Várilly
Forty-five years after the point de départ [1] of density functional theory, its applications in chemistry and the study of electronic structures keep steadily growing. However, th…
