Abstract

Due to its low symmetry C2v, the dowser texture is characterised by a 2D unitary vector field or alternatively by a unitary complex field. For the same symmetry reasons, the dowser texture is sensitive, in first order, to perturbations such as thickness gradients, electric fields or flows. We will focus on corresponding properties called respectively: cuneitropism, electrotropism and rheotropism. In particular we will show that topological defects, known as dowsons or monopoles, can be manipulated by means of these tropisms.

摘要

由于其低对称性C2v，探矿者纹理的特征是二维酉向量场，或者由酉复场表示。出于同样的对称原因，探矿者纹理在一阶近似下对诸如厚度梯度、电场或流动等扰动敏感。我们将关注分别称为：楔向性、电向性和流变性的相应特性。特别是我们将表明，被称为道森或单极子的拓扑缺陷可以通过这些向性来操纵。
