Electronic Charge Transport in Extended Nematic Liquid Crystals
Kai Lin Woon,Matthew P. Aldred,Panos Vlachos,Georg H. Mehl,Thomas Stirner,Stephen M. Kelly,Mary O'Neill +6 more
TL;DR: In this paper, the authors showed that the hole mobility is independent of the macroscopic, but not microscopic, ordering of the nematic and isotropic phases of these nematic liquid crystals with a long, rigid and extended aromatic molecular core.

Poisson-bracket approach to the dynamics of nematic liquid crystals.
Holger Stark,Tom C. Lubensky +1 more
TL;DR: The general Poisson-bracket formalism is used to derive the equations that govern the dynamics of nematic liquid crystals in both their nematic and isotropic phases and it is shown that the full nonlinear hydrodynamical equations for the nematic phase derived are identical to the nonlinear Ericksen-Leslie equations.

The Elastic Constants of Maier-Saupe Rodlike Molecule Nematics
G. Marrucci,Francesco Greco +1 more
TL;DR: In this article, the Maier-Saupe theory of spatially uniform nernatics is extended to the case of distorted configurations and the mean field potential is defined as an average over a suitable neighborhood of the test molecule.

Magnetic-field-induced orientational order in the isotropic phase of hard colloidal platelets.
D. van der Beek,Andrei V. Petukhov,Patrick Davidson,Jacques Ferré,J. P. Jamet,Henricus H. Wensink,Gert Jan Vroege,Wim Bras,Henk N. W. Lekkerkerker +8 more
TL;DR: The magnetic-field-induced orientational order in the isotropic phase of colloidal gibbsite [Al(OH)3] platelets is studied by means of optical birefringence and small-angle x-ray scattering techniques, which leads to an underestimate of the diamagnetic susceptibility anisotropy Delta(chi).
Journal ArticleDOI
Instabilities and nonlinear dynamics of concentrated active suspensions
TL;DR: In this paper, the role of steric vs hydrodynamic interactions in these dense systems is addressed using a continuum theory and numerical simulations, in which a conservation equation for the distribution function of particle configurations is coupled to the Stokes equations for the fluid motion.

Nuclear relaxation in a nematic liquid crystal
TL;DR: In this paper, the authors estimate the contributions to T1 and T2 in a nematic liquid crystal arising from the fluctuations in the orientational order, which results in relaxation times of the order of one second which is typical of ordinary liquids.

Quasielastic Rayleigh Scattering in Nematic Liquid Crystals
TL;DR: Using a light-beat laser spectrometer, the authors observed the relaxation of the thermally excited fluctuations of anisotropy in the nematic phase of $p\ensuremath{-}\mathrm{azoxyanisole}$.
