Abstract The influence of randomly distributed impurities on liquid crystal (LC) orientational ordering is studied using a simple Lebwohl-Lasher t5q)e lattice model in two d=2) and three d=3) dimensions. The impurities of concentration p impose a random anisotropy field-type of disorder of strength w to the LC nematic phase. Orientational correlations can be well presented by a single coherence length for a weak enough w. We show that the Imry-Ma... 

Our simulations use a lattiee-spin model of a liquid erystal, of the t5q)e pioneered by Lebwohl and Lasher. We use a simple Lebwohl-Lasher pairwise interaetion among rod-like lattiee spins S,. The nature of the energy means that, as with all liquid erystal systems, there is never a distinction between S and - S. This ean simulate either a thermotropie or a lyotropic LC. The sites are arranged in a ri-dimensional eubie lattiee, of length L lattice constants, with total number of sites (i.e. partieles) N = lf, subjeet to periodic boundary conditions. In all subsequent work, distanees are scaled with respect to the lattiee eonstant. 

In the quest for a universal feature in the short-to-intermediate time orientational dynamics of thermotropic liquid crystals across the I-N transition, Chakrabarti et al. [115] investigated a model discotic system as well as a lattice system. As a representative discotic system, a system of oblate ellipsoids of revolution was chosen. These ellipsoids interact with each other via a modified form of the GB pair potential, GBDII, which was suggested for disc-like molecules by Bates and Luckhurst [116]. The parameterization, which was employed for the model discotic system, was k = 0.345, Kf = 0.2, /jl= 1, and v = 2. For the lattice system, the well-known Lebwohl-Lasher (LL) model was chosen [117]. In this model, the particles are assumed to have uniaxial symmetry and represented by three-dimensional spins, located at the sites of a simple cubic lattice, interacting through a pair potential of the form...
