Effect of Van der Waals forces on the lattice dynamics and crystal structure of noble metals

The effect of Van der Waals forces on the lattice dynamics and crystal structure of noble metals has been studied in the formalism of Rehr, Zaremba and Kohn. When the contribution of these forces is included in the resonant model potential scheme, the phonon frequencies are lowered by 5–8% and the crystal structure is still found to be the observed one (f.c.c.) for noble metals.
