Mesoscopic structure of liquid–vapour interfaces

At the molecular scale, liquid–vapour interfaces are broadened and roughened by thermally excited capillary waves. These fluctuations give rise to a divergence of the interfacial structure factor at small wave-numbers; the latter being accessible to grazing-incidence small-angle X-ray scattering (GISAXS) experiments. The paper discusses deviations from the classical theory and relies on extensive simulations of planar interfaces using up to 445,000 Lennard-Jones particles. GISAXS intensities are computed on the fly of the simulations.
