ABSTRACT
Monte Carlo simulations of a system of 2500 parallel cut spheres of thickness L/D=0.1 give evidence for a phase transition, at packing fraction η∼0.40, from the low density nematic phase to a smectic phase. No tendency to formation of columnar ordering is observed up to densities as high as η=0.60. This behavior contrasts with that of freely rotating cut spheres for which the sequence of stable phases has been identified as isotropic–nematic–columnar–solid [D. Frenkel, Liquid Cryst. 5, 929 (1989)]. For the present system of highly anisotropic molecules the slow convergence of the expansion of correlation functions on rotational invariants precludes quantitative comparison between integral equation theory and simulation results.

    When a polymer chain is confined to a box with sides Lx≠Ly=Lz whose dimensions are small compared to the chain radius of gyration, it gives rise to unequal pressure components, Px≠Py=Pz, where Px is the pressure acting on a face perpendicular to the x axis. This problem is treated...
