Demixed and ordered phases in hard-rod mixtures

摘要: We analyse demixing and ordering transitions in systems of hard cylindrical particles. The second virial approximation Onsager a bifurcation analysis, as introduced by Koda Kimura, are used to evaluate the free energies, pressures, density distribution functions mixtures equally long but differently wide cylinders. spatial along one relevant coordinate is particular importance it provides more detailed information concerning nature phase transition than bare diagnosis. Detailed results given for nematic–nematic spinodal nematic–smectic transitions. Allowing absence an isotropic phase, our good qualitative agreement with those freely orienting rods reported previously, indicate complex sequence diagrams diameter dissimilarity two components increased, upper lower critical points bounding nematic smectic regions. However, exper...
