Conditional entropies and position–momentum correlations in atomic systems
Robin P. Sagar, Humberto G. Laguna, Nicolais L. Guevara · Molecular Physics · 2009
We show via Wigner functions how the sum and difference between Shannon entropies in position and in momentum space are related to conditional entropies, and how these quantities are linked to position–momentum correlations. The connection between Fermi, Coulomb and position–momentum correlations on these quantities is made, and the impact of these are discussed in atomic systems.
