Isotropic-Nematic Transition in Liquid Crystals
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
Zhengju Yang,Guangquen Ma +1 more
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.

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.
