Effect of the Coupling Between Director and Mass Density Fluctuations on the Paranematic–Nematic Transition Temperature: A Mean-field Treatment
TL;DR: In this paper, a generalization of the Landau-de-Gennes theory that incorporates mass density fluctuations was proposed to calculate the contribution of this mechanism to the Helmholtz free energy.

Relaxation of the Alignment Tensor in the Isotropic and Nematic Phases of Liquid Crystals in the Presence of an External Field
P. Kaiser,S. Hess +1 more
TL;DR: In this paper, the second-order alignment tensor is analyzed in the presence of an external magnetic field, and the results show that the acceleration of the relaxation process is fast, later on slowly, and then fast again for some values of the temperature.

Size and surface effect in nematic‐isotropic phase transition of a liquid crystal
TL;DR: In this article, the size and surface effects on the nematicisotropic phase transition of a liquid crystal are analyzed using a functional form of the surface energy proportional to the square of the scalar order parameter.

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.
