Intermolecular Casimir-Polder forces in water and near surfaces

Thiyam, P.; Persson, Clas; Sernelius, B; Parsons, Drew; Malthe-Sorenssen, Anders; Bostrom, Mathias


The Casimir-Polder force is an important long-range interaction involved in adsorption and desorption of molecules in fluids. We explore Casimir-Polder interactions between methane molecules in water, and between a molecule in water near SiO2 and hexane surfaces. Inclusion of the finite molecular size in the expression for the Casimir-Polder energy leads to estimates of the dispersion contribution to the binding energies between molecules and between one molecule and a planar surface.
