Fluid structure from density-functional theory
We treat various common fluid models, like the inverse-power, Asakura-Oosawa, and Lennard-Jones potentials, within the soft fundamental measure theory (SFMT). We show that this recently proposed density-functional approach is able to predict the pair correlations in the fluid phase reliably compared to computer simulations. Explicit expressions for certain quantities of SFMT are given, namely, for the weight functions and the fundamental measures. These technical tools permit practical calculations for a large class of inhomogeneous systems.
