Nematic ordering problem as the polymer problem of the excluded volume

Autor: Andrei N. Yakunin

Publikováno v: Open Physics, Vol 1, Iss 2, Pp 355-362 (2003)

Based on a solution of the polymer excluded volume problem, a technique is proposed to estimate some parameters at the isotropic-nematic liquid crystal phase transition (the product of the volume fraction of hard sticks and the ratio of the stick len

Chiral smectic liquid crystals exhibit a series of phases, including ferroelectric, antiferroelectric, and ferrielectric commensurate structures as well as an incommensurate $\text{Sm-}{C}_{\ensuremath{\alpha}}^{\ensuremath{\ast}}$ phase. We carried

Effect of Dipolar Interaction in Molecular Crystals

Autor: Hoang, Danh-Tai, Diep, Hung The

We investigate in this paper the ground state and the nature of the transition from an orientational ordered phase at low temperature to the disordered state at high temperature in a molecular crystal. Our model is a Potts model which takes into acco

Journal of Non-Newtonian Fluid Mechanics, Elsevier, 2008, 149 (1-3), pp.40-55. ⟨10.1016/j.jnnfm.2007.05.007⟩

We propose a rational approach to approximating the various alignment tensors. It preserves the correct symmetry and leads to consistent results. For the case of uniaxial nematic fluids, the decoupling approximation for a tensor of rank n involves (

Discontinuous change in smectic layer thickness in ferrielectric liquid crystals

Autor: Yu. P. Panarin, Christophe Blanc, Jagdish K. Vij, John W. Goodby, Vitaly P. Panov, Vladimir Lorman

PUBLISHED
The temperature dependence of the thickness of thick free-standing films is studied using a high-resolution film thickness measurement technique. A small discontinuity in the temperature dependence of the smectic layer thickness at eve
