Abstract

Metamaterials have subwavelength periodic structures that manipulate electromagnetic waves. Typically, difficulties are encountered in fabricating this type of materials due to the sophisticated techniques involved in their creation. Bubble domains in chiral nematic liquid crystals present a skyrmion lattice which has periodicity regions along a cell, which allow the observation of unconventional light-matter interaction. However, the interaction dynamics between vortices presents a challenge to ensure the order of the lattice throughout the space it covers. In this work we study the use of liquid crystal microdroplets as potential wells and the clustering of topological defects in them.
手性向列液晶微滴中的涡旋聚类
超材料具有操纵电磁波的亚波长周期结构。通常情况下,在制造这类材料时遇到的困难是由于它们的创造所涉及的复杂技术。手性向列液晶中的气泡域呈现出一个具有周期性区域的斯基子晶格,它允许观察非常规的光-物质相互作用。然而,涡旋之间的相互作用动力学提出了一个挑战,以确保整个空间中晶格的顺序。本文研究了利用液晶微滴作为势阱及其拓扑缺陷的聚类。
