重入向列相的结构和动力学：近40年后有什么悬而未决的问题吗？
Structure and dynamics of reentrant nematics: Any open questions after almost 40 years?
摘要：
液晶由于其相态的多样性和应用的丰富性而引起了人们极大的兴趣。一般物理对称性和特定分子特征的相互作用产生了无数不同的现象。液晶的一个令人惊讶的行为是当温度、压力或浓度变化时相的重入性。在这里，我们回顾了主要的实验事实和不同的理论方案，指导理解散装重入向列相。最近，一些局限于纳米尺度的系统的计算机模拟发现了新的动力学特征的重入的双相。我们讨论了这个预测与现有的实验证据，可重入向列相，并在强封闭环境中的液体动力学。
英文摘要：
Liquid crystals have attracted enormous interest because of the variety of their phases and richness of their application. The interplay of general physical symmetries and specific molecular features generates a myriad of different phenomena. A surprising behavior of liquid crystals is the reentrancy of phases as temperature, pressure, or concentration are varied. Here, we review the main experimental facts and the different theoretical scenarios that have guided the understanding of bulk reentrant nematics. Recently, some computer simulations of a system confined to nanoscopic scales have found new dynamical features of the reentrant nematic phase. We discuss this prediction in relation with the available experimental evidence on reentrant nematics and with the dynamics of liquids in strongly confined environments.
