Zusammenfassung:
Recent experiments on non-covalent interactions at the nanoscale have chal-
lenged the basic assumptions of commonly used particle- or fragment-based
models for describing van der Waals (vdW) or dispersion forces. We demon-
strate that a qualitatively correct description of the vdWinteractions between
polarizable nanostructures over a wide range of finite distances can only be
attained by accounting for the wavelike nature of charge density fluctuations.
By considering a diverse set of materials and biological systems with markedly
different dimensionalities, topologies, and polarizabilities, we find a visible en-
hancement in the non-locality of the charge density response in the range of
10 to 20 nanometers. These collective wavelike fluctuations are responsible for the emergence of non-trivial modifications of the power laws which govern
non-covalent interactions at the nanoscale.
