Abstract

We review the theoretical research on the influence of disorder on structure and phase behavior of condensed matter system exhibiting continuous symmetry breaking focusing on liquid crystal phase transitions. We discuss the main properties of liquid crystals as adequate systems in which several open questions with respect to the impact of disorder on universal phase and structural behavior could be explored. Main advantages of liquid crystalline materials and different experimental realizations of random field-type disorder imposed on liquid crystal phases are described.

摘要

我们回顾了关于无序对表现出连续对称破缺的凝聚态物质系统的结构和相行为的影响的理论研究，重点关注液晶相变。我们讨论了液晶作为适当体系的主要性质，在这些体系中，可以探索关于无序对普遍相和结构行为的影响的几个悬而未决的问题。描述了液晶材料的主要优点和对液晶相施加的随机场型无序的不同实验实现。
