圆环面上nematic liquid crystals的平衡构型

Equilibrium configurations of nematic liquid crystals on a torus

Antonio Segatti, Michael Snarski, Marco Veneroni

摘要:

表面的拓扑结构和几何形状在决定液晶薄膜的平衡构型中起着基本的作用。我们建议在这里的理论分析最近推出的表面弗兰克能源,在二维液晶液晶涂层的环形粒子的情况下。我们的目的是展示如何一个不同的模型的影响,外在的曲率作为一个选择原则之间的平衡的经典能量,以及如何出现新的配置。特别是,我们的分析预测存在新的稳定平衡与复杂的绕组。

英文摘要:

The topology and the geometry of a surface play a fundamental role in determining the equilibrium configurations of thin films of liquid crystals. We propose here a theoretical analysis of a recently introduced surface Frank energy, in the case of two-dimensional nematic liquid crystals coating a toroidal particle. Our aim is to show how a different modeling of the effect of extrinsic curvature acts as a selection principle among equilibria of the classical energy, and how new configurations emerge. In particular, our analysis predicts the existence of new stable equilibria with complex windings.
