摘要

通过手性液晶的Landau-Ginzburg-de Gennes理论和Lech Longa的简化手性模型理论在四阶累积展开的帮助下给出蓝相Ⅲ到各向同性相相变系统自由能高阶项的计算结果

分析了相变比热与约化温度的关系

得出了蓝相Ⅲ到各向同性相的相变结束于一临界点

从而说明蓝相Ⅲ为各向同性相。

Abstract

According to the phenomenological theory of Landau-Ginzburg-de Genns and a simplified model of Lech Longa

this work got the system free energy within the four-order self-consistent cumulant expansion. The relationship between the specific heat and reduced temperature was researched. It is found that blue phase Ⅲ to isotropic phase transition ends at a critical point. So blue phase Ⅲ is a isotropic phase.
