Molecular field theory of nematics: density functional approach. I. Bulk effects
TL;DR: In this article, the free energy in the nematic state is expressed as a functional expansion around the isotropic state in powers of the Nematic order parameters Pl and the fractional density change eta.

Hydrodynamics and correlation functions in ordered systems: Nematic liquid crystals☆
TL;DR: In this paper, a rigorous hydrodynamic theory is presented which is formulated and derived, from the start, in terms of measurable correlation functions, and applied easily also to other ordered systems like glasses, isotropic ferro-and antiferromagnets, superfluids, and, of course, normal fluids.

Morphological transitions in liquid crystal nanodroplets
TL;DR: In this paper, a continuum theory is used to study ordering in liquid crystal nanodroplets and the free energy functional that describes the system is minimized using an Euler-Lagrange approach and an unsymmetric radial basis function method.
Journal ArticleDOI
Ultrasonic investigation of the nematic‐isotropic phase transition in MBBA
TL;DR: In this article, the authors investigated the relaxation processes associated with the nematicisotropic phase transition in liquid crystals of p-methoxybenzylidine-p-n-butylaniline.
Journal ArticleDOI
A generalisation of the Onsager trial-function approach: describing nematic liquid crystals with an algebraic equation of state
TL;DR: Onsager's theory was originally developed at the level of the second virial coefficient; here the Parsons-Lee decoupling approximation is used to describe the higher degree of anisotropy as discussed by the authors.

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