A simple model of a fluid consisting of two-level atoms, for which changes in their interaction due to a resonance irradiation can be found in the framework of the quantum-mechanical perturbation theory is considered, and the corresponding functional for the grand thermodynamic potential is found. The density functional method is used to calculate the surface tension at the liquid–vapor, solid–liquid, and solid–vapor interfaces, and the Young equation is applied to determine the wetting angle. It is shown that the resonance irradiation can significantly increase the latter parameter.</p> ER -
