Phenomenology of short-range-order effects in the isotropic phase of nematic materials
TLDR
In this article, the magnetic birefringence, the intensity and the width in frequency of the Rayleigh scattering, and the flow bireringence are discussed in terms of a small number of phenomenological parameters.About:

Dynamic Viscoelastic Properties of Cholesteric Liquid Crystals
Joseph F. Dyro,Peter D. Edmonds +1 more
TL;DR: In this article, the propagation of ultrasonic shear waves at frequencies from 24 to 18 MHz was studied in three 18-carbon unsaturated fatty acid esters of cholesterol, including cholesteryl obleate (CO), cholesterol linoleacte (CL), and cholestery linolenate (CLn), and three mixtures of the esters, including oleate and linoleate esters containing about 70-80% of the cholesterol contained in atherosclerotic plaque.

Isotropic ferromagnets with biquadratic interactions
TL;DR: In this paper, a spin-one Heisenberg ferromagnet with biquadratic exchange is investigated, using Green's function technique in the Callen decoupling approximation.
Journal ArticleDOI
Stress tensor of dilute polymer solutions
TL;DR: The Kramers-Giesekus tensor is shown to be incompatible with an Oldroyd time derivative in the evolution equation of polymer deformation as discussed by the authors, which is the same as the one used in this paper.

Magnetic field-induced changes in molecular order in nematic liquid crystals
TL;DR: In this paper, the boundary layer between the cell substrate and the bulk nematic material was investigated and the authors were able to analytically determine the director and scalar order parameter configurations for the majority of field strengths and where analytical solutions are not found a numerical solution is presented.

Gravitationally self-induced phase transition
M. Novello,S.L.S. Duque +1 more
TL;DR: In this article, a new mechanism was proposed by means of which a phase transition can be stimulated by self-gravitating matter, which could be used to explain the observed isotropy of the universe.

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 $p\ensuremath{-}\mathrm{azoxyanisole}$.
