Pattern Formation in Active Nematics
… of active nematic liquid crystals. Active nematics are a new class of liquid crystals consisting of elongated rod-like units that convert energy into motion and spontaneously organize in large-scale structures with orientational order and self-sustained flows. Examples include suspensions …

Mathematical modelling of active nematic liquid crystals in confined regions
… spontaneous flow transitions of active nematics, with the liquid crystal confined in a one-dimensional shallow channel. We examine how internally generated flows induced by activity are affected by externally induced flows due to, pressure gradients and external orienting fields. We then …

A study of processing methods for producing biaxial orientation in thermotropic liquid crystalline polymers
… for these thermotropic systems. Doi's theory of nematics, although limited to monodomains and containing numerous mathematical approximations in order to obtain a closed form for the kinetic equation, was used to predict the orientation development in the blown film process. Although qualitative …

Neutron scattering and thermodynamic studies of quantum magnetism on the kagomé lattice
… states such as quantum spin liquids and spin nematics. Thermodynamic measurements were performed on the antiferromagnetic kagome materials MgxCu₄-x(OH)₆ Cl₂ , featuring S = 1/2 moments. These measurements reveal magnetic ordering at low values of x that is suppressed with increasing x. At x = …

The role of topological defects and textures in the kinetics of phase ordering
… in 2- and 3-d.imensional uniaxial and biaxial nematics are presented. The second system studied-the Heisenberg-type model in 2 spatial dimensionsis first implemented numerically as the discretized 0(3) nonlinear u-model with the standard form of free energy and with purely dissipative dynamics. …

Nonlinear optical studies of dye-doped nematic liquid crystals
… than what has been observed in other dye-doped nematics and other liquid crystal/polymer systems. All the samples showed a threshold behavior with respect to the magnitude of the applied electric field. This threshold behavior was observed both in forced light scattering experiments and …
