We show that electrodynamic dipolar interactions, responsible for long-range fluctuations in matter, play a significant role in the stability of molecular crystals. Density functional theory calculations with van der Waals interactions determined from a semilocal “atom-in-a-molecule” model result in a large overestimation of the dielectric constants and sublimation enthalpies for polyacene crystals from naphthalene to pentacene, whereas an accurate treatment of nonlocal electrodynamic response…

Many-body van der Waals interactions in molecules and condensed matter.

This work reviews the increasing evidence that many-body van der Waals or dispersion interactions play a crucial role in the structure, stability and function of a wide variety of systems in biology, chemistry and physics and provides a roadmap for navigating many of the research avenues that are yet to be explored.

Many-body dispersion interactions in molecular crystal polymorphism.

It is shown that accounting for the nonadditive many-body dispersion (MBD) energy beyond the standard pairwise approximation is crucial for the correct qualitative and quantitative description of polymorphism in molecular crystals.

Understanding the structure and electronic properties of molecular crystals under pressure: application of dispersion corrected DFT to oligoacenes.

It is concluded that none of the oligoacenes investigated become conducting under elevated pressures, assuming that the molecular identity of the system is maintained.

Assessing the performance of density functional theory in optimizing molecular crystal structure parameters.

The results demonstrate that the PBE functional is capable of returning reliable full structural optimizations, in which both atomic positions and unit-cell vectors are free to optimize simultaneously.
