Density functional theory for the freezing of soft-core fluids

By Andrew J. Archer


This article was published in the journal, Physical Review E [© The American Physical Society] and is also available at: present a simple density functional theory for the solid phases of systems of particles interacting via soft-core potentials. In particular, we apply the theory to particles interacting via repulsive point Yukawa and Gaussian pair potentials. We find qualitative agreement with the established phase diagrams for these systems. The theory is able to account for the bcc-fcc solid transitions of both systems and the re-entrant melting that the Gaussian system exhibits. © 2005 The American Physical Society
