Ab-initio density-functional theory for penetrable spheres M. Schmidt, J. Phys.: Condens. Matt. 11, 10163 (1999). Locate in [bare] [illustrated] list. Get [full paper] as pdf. Extract. We develop a density functional theory for a system of penetrable spheres that interact with a constant pair potential energy if their separation distance is smaller than their diameter. The theory predicts the bulk fluid properties in good agreement with computer simulations, as well as the freezing transition to a multiply occupied face-centred-cubic lattice.

Basic model fluids
Density functionals were constructed for hard spheres [5] [6], penetrable spheres that interact with a step-function pair potential [7] (see [14] for more discussion), the Asakura-Oosawa-Vrij model of colloid-polymer mixtures [11], the Widom-Rowlinson model [17], and non-additive hard sphere mixtures [53].[more]
