Density functional theory of crystallization: from anisotropic particles to polymers — •Hartmut Loewen — Universitaetsstrasse 1, 40225 Duesseldorf

Classical density functional theory for freezing is used to predict the equilibrium bulk phase diagram of anisotropic particles. Explicit results are obtained for orientable hard rectangles in 2 spatial dimensions where isotropic, nematic and smectic phases do occur as a function of particle aspect ratio and number density. Then the density functional theory is applied to the smectic phase on a nontrivial curved manifold like a cone. Confinement-induced phase transition are calculated. Last, ideas to extent the theory towards polymer crystallization are described.
