Universal variational functionals of electron densities, first-order density matrices, and natural spin-orbitals and solution of the v-representability problem

Universal variational functionals of densities, first-order density matrices, and natural spin-orbitals are explicitly displayed for variational calculations of ground states of interacting electrons in atoms, molecules, and solids. In all cases, the functionals search for constrained minima. In par...
