缓解平面中的向列几何阻挫

Relieving nematic geometric frustration in the plane

Andrea Pedrini, Epifanio G. Virga

AI总结:

本文在二维平坦空间中用纯几何方法研究向列介质阻挫,证明平面螺旋是唯一能填满全平面的准均匀畸变,其余缓解畸变仅限半平面且渐近为螺旋。

摘要:

在平坦二维空间中,以纯几何方式处理向列有序介质(具有指向矢场)中的阻挫。我们回顾准均匀畸变的定义,并将其视为缓解在直线或单位圆上规定的指向矢场的可行方法。我们证明,使用平面螺旋是唯一能以一种准均匀畸变填满整个平面的方式。除此之外,所有缓解性的准均匀畸变至多能在半平面内定义;然而,在一般意义上,它们都是渐近螺旋。

英文摘要:

Frustration in nematic-ordered media (endowed with a director field) is treated in a purely geometric fashion in a flat, two-dimensional space. We recall the definition of quasi-uniform distortions and envision these as viable ways to relieve director fields prescribed on either a straight line or the unit circle. We prove that using a planar spiral is the only way to fill the whole plane with a quasi-uniform distortion. Apart from that, all relieving quasi-uniform distortions can at most be defined in a half-plane; however, in a generic sense, they are all asymptotically spirals.
