Nucleation in a colloidal hard sphere system using density functional theory — •Andreas Härtel¹, Martin Oettel², and Hartmut Löwen¹ — ¹Institut für Theoretische Physik II: Weiche Materie, Heinrich-Heine-Universität Düsseldorf, Germany — ²Institut für Physik, Johannes-Gutenberg-Universität Mainz, Germany

The fluid-solid interface in a system of hard spheres is studied by density functional theory. For this purpose we employ a free minimization [1] of the White Bear II fundamental measure density functional [2] and perform a comparative study using Monte Carlo simulations [3]. Both the bulk freezing transition and the structure and thermodynamics of the hard sphere fluid-solid interface are discussed and compared to simulation data.
