Inclusion of density variation in the Landau-de Gennes theory of the nematic-isotropic phase transition.
Journal ArticleDOI
A Molecular Mean Field Theory of Reentrant Phases
TL;DR: In this article, the observed phase transition sequence N-SA-Nre Sre with a lowering in temperature in pure compounds of molecules with a strongly polar end group is reproduced in a mean field model which is taken as an extension of the McMillan potential.
Journal ArticleDOI
Role of end chains in the reentrant behavior of a nonpolar system.
TL;DR: These theories essentially show that the high-temperature smectic phase is an induced phase and the reentrant nematic phase is brought about by a competition between two incommensurate lengths.
Journal ArticleDOI
Monte-Carlo Simulation of the Cholesteric Phase in Liquid Crystals
TL;DR: In this paper, a simple pair interaction potential between chiral molecules was used to generate a cholesteric configuration of molecules in a 15 × 15 ×15 × 15 system, and the effect of temperature on the structure was studied.
Journal ArticleDOI
Chain ordering and smectic a phase
TL;DR: Marcelja's theory for nematic-isotropic transitions has been extended to the case of the smectic A phase as mentioned in this paper, where members of a homologous series can be treated individually and their Sm-N, N-I transitions studied.
