On the basis of the adiabatic connection formula we propose several approximations for the total correlation energy functional, which, in the limit of two separated neutral subsystems, correctly reproduce the van der Waals R y6 behavior. We have calculated the corresponding van der Waals coefficient
We use the density functional theory to invest&te the ground state cner,g of 5 psir of intemcting electronic syslcr;ls ;ct large distanCcs from one another. We prove that a simple mean field approximation to the electron density is sufficient to determine the6(1/R3) and(i(l/R$) behavior of the groun
