An alternative well founded way to treat the center-of-mass
correlations: proposition of a local center-of-mass correlations potential    [PDF]

Jeremie Messud

The recently developped "internal" Density Functional Theory provides an existence theorem for a local potential that contains the center-of-mass correlations effects. The knowledge of the corresponding energy functional would provide a much cheaper way than projection techniques to treat those correlations. The aim of this article is to construct such a functional. We propose a well founded method, suitable for Fermions as well as for Bosons, which does not necessit to include any free parameter.
