A molecular dynamics simulation study on nematic-isotropic phase transition of rod-like molecules in NpT ensemble
S. H. Lee,H. S. Kim,Hyuk Kyu Pak +2 more
TL;DR: In this article, a more realistic model than a hard core system is employed to calculate time-dependent functions and an isothermal-isobaric (NpT) ensemble is used to consider the change of volume at the NpT transition.

Light scattering, flow birefringence and generalized hydrodynamics
TL;DR: In this article, the stress-optical coefficient ∇, which is measured in flow birefringence experiments, is calculated using the generalized hydrodynamic equations which have been recently used to explain the k-dependent fine structure observed in depolarized (VH) light scattering.

Nonlinear Dielectric Effect in Critical Liquids
TL;DR: The nonlinear dielectric effect (NDE) describes changes of dielectrics constant under the strong electric field, with the metric defined in this paper, where the authors discuss miscibility, the isotropic phase of nematic liquid crystals, and supercooled nitrobenzene.

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.
