Orientational order in dipolar fluids consisting of nonspherical hard particles
We investigate fluids of dipolar hard particles by a certain variant of density-functional theory. The proper treatment of the long range of the dipo-lar interactions yields a contribution to the free energy which favors ferromag-netic order. This corrects previous theoretical analyses. We determine phase diagrams for dipolar ellipsoids and spherocylinders as a function of the aspect ratio of t...
متن کاملComment on "Long-ranged orientational order in dipolar fluids"
Recently Groh and Dietrich[1] calculated orientational order transitions for dipolar fluids contained in spheroidal shapes of aspect ratio k. According to their study the thermodynamic state of a dipolar fluid depends on the shape of the fluid's container. For example, a homogeneous fluid in a short fat container would phase separate when transferred to a tall skinny container of identical volu...
متن کاملDensity functional theory of charged, hard-sphere fluids.
An approximate electrostatic (ES) excess free energy functional for charged, hard sphere fluids is presented. This functional is designed for systems with large density variations, but may also be applied to systems without such variations. Based on the Rosenfeld method of perturbation about a bulk (homogeneous) reference fluid [Y. Rosenfeld, J. Chem. Phys. 98, 8126 (1993)], the new ES function...
متن کاملThe Chiral Dipolar Hard Sphere Model
A simple molecular model of chiral molecules is presented in this paper : the chiral dipolar hard sphere model. The discriminatory interaction between enantiomers is represented by electrostatic (or magnetic) dipoles-dipoles interactions : short ranged steric repulsion are represented by hard sphere potential and, in each molecule, two point dipoles are located inside the sphere. The model is d...
متن کاملOptimal packing of polydisperse hard-sphere fluids
We consider the effect of intermolecular interactions on the optimal size-distribution of N hard spheres that occupy a fixed total volume. When we minimize the free-energy of this system, within the Percus–Yevick approximation, we find that no solution exists beyond a quite low threshold (h'0.260). Monte Carlo simulations reveal that beyond this density, the size-distribution becomes bimodal. S...
