Maier-Saupe theory in four dimensions.
Maier-Saupe theory is the canonical mean field description of thermotropic nematic liquid crystals. In this paper, we examine the predictions of the theory in four spatial dimensions. Representations of the order parameter tensor and the existence of new phases are discussed. The phase diagram, based on numerical solution of the self-consistent equations and Landau theory, is presented. Orienta...
متن کاملAn Investigation of MBBA nematic within Generalized Maier-Saupe Theory
Generalized Maier-Saupe theory (GMST) within Tsallis thermostatistics (TT) has been used to investigate the second rank order parameter in a nematic liquid crystal, N-p-methoxybenzylidene p-n-butylaniline (MBBA). Also, the free energy has been investigated at the nematic-isotropic phase transition temperature and the effect of the nonextensivity has been demonstrated. PACS Number(s): 05.20.-y, ...
متن کاملPhase behavior of a hard sphere Maier-Saupe nematogenic system in three dimensions.
We present a detailed computer simulation and integral equation study of the phase behavior of a nematogenic system composed of hard spheres with embedded three-dimensional Maier-Saupe spins. For this well-known system, we map the gas-liquid equilibrium, which is coupled to a first-order isotropic-nematic transition. The anisotropic integral equation theory is found to yield excellent agreement...
متن کاملGeneralization of the Maier-Saupe theory of the nematics within Tsallis Thermostatistics
In this study, one of the mean-field theories in nematics, the Maier-Saupe theory (MST), is generalized within Tsallis Thermostatistics (TT). The variation of the order parameter versus temperature has been investigated and compared with experimental data for PAA (p-azoxyanisole). So far we believe that this is the first attempt of the application of TT in liquid crystals. It is well known that...
متن کاملMaier-Saupe-type theory of ferroelectric nanoparticles in nematic liquid crystals.
Several experiments have reported that ferroelectric nanoparticles have drastic effects on nematic liquid crystals-increasing the isotropic-nematic transition temperature by about 5 K, and greatly increasing the sensitivity to applied electric fields. In a recent paper [Lopatina and Selinger, Phys. Rev. Lett. 102, 197802 (2009)], we modeled these effects through a Landau theory, based on couple...
