A density functional for additive mixtures M. Schmidt, Phys. Rev. E 62, 3799 (2000). Locate in [bare] [illustrated] list. Get [full paper] as pdf. Extract. We present a density functional theory for mixtures of particles interacting with a radially symmetric pair potential. The approach is suitable for systems with soft or hard interactions between like species. The cross interactions between unlike species are restricted to obey an additivity constraint.

DFT for soft potentials
Based on the hard sphere case [5] [6], a density functional theory (DFT) for soft (i.e. continuously varying as a function of interparticle distance) potentials was obtained by considering dimensional crossover [8], and subsequently extended to mixtures [10]. Applications concern the liquid structure of model fluids [13], and structure and freezing of star polymer solutions [15] (see also [16].)[more]
