In continuation of earlier work. an atomistic derivation is given of Lifshitz' formula for the non-retarded Van der Waals interaction between two semi-infinite dieIectric media. In the derivation an atom is supposed to consist of a number of isotropic harmonic oscillators.
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
