Abstract

Defect dynamics in a thin active nematic layer is studied by asymptotic matching of solutions in the defect core and the far field. The analysis is facilitated by the correspondence between the two-dimensional nematic and complex scalar field models. Self-propulsion and topological interactions are identified as the primary drivers of the defect motion, surpassing the influence of both passive backflow and active flow induced by other defects.

摘要

通过对缺陷核心和远场中解的渐近匹配,研究了薄活性向列层中的缺陷动力学。二维向列模型与复标量场模型之间的对应关系有助于进行分析。自推进和拓扑相互作用被确定为缺陷运动的主要驱动力,超过了其他缺陷引起的被动回流和主动流动的影响。
