Investigation on Liquid Crystalline Systems

Abstract

The results of experiments carried out by us on two samples exhibiting a macroscopic helical structure.While one of them shows a direct transition from chiral orientationally ordered fluid(referred to an N* phase) to a phase with one dimensional layer structure,the second sample exhibits a liquid crystal analog of the Abrikosov flux lattice of super conductors,between the N* and layered phase.The chapter compares and contrasts the differences in the behavior of the two compounds.
