## Abstract Ewald summation is used to apply semiempirical longβrange dispersion corrections (Grimme, J Comput Chem 2006, 27, 1787; 2004, 25, 1463) to periodic systems in density functional theory. Using the parameters determined before for molecules and the PerdewβBurkeβErnzerhof functional, struc

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
## The Basic Machinery of Density Functional Programs The preceding six chapters provided an overview of the theoretical background and current state of the art of modern approximate density functional theory. We now turn to the more practical problem of how the strategies developed so far can be
