Closed-form expressions for correlated density matrices: application to dispersive interactions and example of (He)2
Sebastien Ragot, Pierre J. Becker
Empirically correlated density matrices of N-electron systems are investigated. Exact closed-form expressions are derived for the one- and two-electron reduced density matrices fro…
A cluster partitioning method: determination of density matrices of solids and comparison with X-ray experiments
Sebastien Ragot, Jean-Michel Gillet, Pierre J Becker
In this paper we show that 1-electron properties such as Compton profiles and structure factors of crystals can be asymptotically retrieved through cluster-based calculations, foll…
Angular versus radial correlation effects on momentum distributions of light two-electron ions
Sebastien Ragot, Jean-Michel Gillet, Pierre J. Becker
We investigate different correlation mechanisms for two-electron systems and compare their respective effects on various electron distributions. The simplicity of the wave function…
Interpreting Compton anisotropy of ice Ih: a cluster partitioning method
Sebastien Ragot, Jean-Michel Gillet, Pierre J. Becker
We propose a simple cluster-based method with application to calculations of Compton profile anisotropies of ice. The convergence of the method is checked with respect to Crystal95…
