    • Density functional theory (DFT) calculations require a judicious choice of the exchange-correlation functional, since it is not a priori clear, whether the generalized gradient approximation (GGA), hybrid functionals, or the local density approximation (LDA) is most appropriate. In graphite, a well-documented example of a weakly interacting system, LDA reproduces correctly the equilibrium structure and elastic properties, whereas GGA fails in this respect. Van der Waals forces, which play an important role in such systems, are in reality not neglected in DFT, but enter in an approximate way through the exchange-correlation functional. Explicit treatment of van der Waals forces is desirable in systems, where these interactions dominate
