Energy functional based on natural orbitals and occupancies for static properties of nuclei
arXiv:0907.0071 · doi:10.1063/1.3232085
Abstract
The possibility to use functionals of occupation numbers and natural orbitals for interacting fermions is discussed as an alternative to multi-reference energy density functional method. An illustration based on the two-level Lipkin model is discussed.
