    A primitive model for small mesogenic molecules is proposed, consisting of three elements: (i) a rigid rodlike core, modeled as a hard spherocylinder of length/diameter ratio L/D=5; (ii) a flexible end group, consisting of five segments of length D, which is "ideal" in the sense that it has no...

    We present a nonperturbative solution of the rotational diffusion equation for an asymmetric rotor reorienting in a uniaxial liquid crystal, such as a nematic, smectic A or membrane bilayer covering the full range of order parameters from isotropic to complete order for rod-like and plate-like...

    In the Onsager theory for the phase transition from the isotropic fluid to the nematic liquid crystal phase, the Helmholtz free energy of a fluid of hard convex bodies (HCBs) is expressed as the sum of an entropy of a mixing-like term and an energy-like term (from the interaction of the HCBs)....

    We examine the changing immiscibility of Widom–Rowlinson-type model mixtures as the number of components is varied. In these mixtures, molecules interact with molecules of a different component via a hard-core interaction but do not interact with other molecules of the same component at...

    The encapsulation of monomer molecules in liquid crystal droplets dispersed in a thermoplastic matrix provides a convenient method to control the orientation of liquid crystal directors. The imprint of droplet interfaces is obtained by photopolymerization of monomer molecules by means of a...
