Measuring order and biaxiality
نویسنده
چکیده
When one considers systems with orientational order, such as liquid crystals, there are various aspects of the ordering that one wishes to quantify. Two properties of the system that one wishes to identify are its overall director, and the extent to which it exhibits biaxiality. We give an exposition of some standard approaches to these issues suitable for advanced undergraduates or beginning postgraduates.

Phase Diagram and Orientational Order in a Biaxial Lattice Model: A Monte Carlo Study.
We have determined the phase diagram for a lattice system of biaxial particles interacting with a second rank anisotropic potential using Monte Carlo simulations for a number of values of the molecular biaxiality. We find increasing differences from mean field theory as the biaxiality increases. We have also calculated for the first time the full set of second rank biaxial and uniaxial order pa...
متن کاملTemperature-induced sign reversal of biaxiality observed by conoscopy in some ferroelectric Sm-C* liquid crystals.
We have studied various ferroelectric liquid crystals to find the average molecular direction of the shortest axis in the perfectly unwound state by using tilted conoscopic measurements. We find that there exist two types of temperature dependencies of the biaxiality. Some materials exhibit increasing biaxiality while others show decreasing biaxiality with increasing temperature. The former sho...
متن کاملBulk and surface biaxiality in nematic liquid crystals.
Nematic liquid crystals possess three different phases: isotropic, uniaxial, and biaxial. The ground state of most nematics is either isotropic or uniaxial, depending on the external temperature. Nevertheless, biaxial domains have been frequently identified, especially close to defects or external surfaces. In this paper we show that any spatially varying director pattern may be a source of bia...
متن کاملStatics and Kinetics at the Nematic-isotropic Interface: Effects of Biaxiality
We use the Landau-de Gennes theory of a nematic liquid crystal to investigate anew aspects of the properties of the interface between the isotropic and nematic liquid crystal phases of the same uid. The equations of the static interface have been solved, both numerically and using asymptotic analysis, with an emphasis on the inclusion of the order parameter biaxiality on the physical properties...
متن کاملNematic biaxiality in a bent-core material.
The results of a recent investigation of the nematic biaxiality in a bent-core mesogen (A131) are in apparent disagreement with earlier claims. Samples of mesogen A131 used in the two studies were investigated with polarized optical microscopy, conoscopy, carbon-13 NMR, and crossover frequency measurements. The results demonstrate that textural changes associated with the growth of biaxial nema...
