Isotropic-Nematic Transition in Liquid Crystals

S. K. Ghosh
TL;DR: In this paper, the isotropic-nematic (IN) transition in MBBA can be considered as the Bose-Einstein condensation of interacting bosons in the momentum space with the ground state defined at T *, the temperature at which the IN transition actually occurs.

The Kinetic Theory of the Orientational Ordering Phase Transition. The Model and the Kinetic Behavior

TL;DR: Using a simple microscopic model, the kinetic equations of the orientational ordering phase transition are established and the general characters of the kinetic behavior of the first-order and second-order phase transitions are obtained.

New variational problems in the statics of liquid crystals

TL;DR: In this article, the authors restrict attention to only one of these phases: nematic liquid crystals, which exhibit a preferred direction, possibly different at each place, and define a field of B into S 2 the unit sphere in the translation space of the 3D Euclidean space.

Director Fluctuations and Spin Relaxation

TL;DR: In this paper, it was shown that the magnitudes of the motional frequency components at the Larmor frequency, at twice this frequency, and at zero frequency are important in NMR relaxation.

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