Direct correlations of the capillary wave model and construction of the free energy density functional for the liquid-vapor interface system

Research output: Contribution to journalArticle


We use the capillary wave model of a liquid-vapor interface as a working example to show how to construct the free energy density functional from studies of the direct correlation functions of a reference system, and vise versa.
