Density functional theory (DFT), in principle, includes Van der Waals
energies, but approximations rooted in the local density approximation
(LDA), such as generalized gradient approximations (GGAs) do not. This
talk will describe recent and ongoing work to use time-dependent density
functional theory to calculate Van der Waals attractions between two
systems of interacting atoms, molecules, clusters, solids, etc., of
arbitrary sizes and shapes.
