摘要:
天纹粒子是二维系统中的拓扑孤子,已在多种物理系统中被观测到。在人工共振器阵列中生成和控制天纹粒子导致了新型声学、光子和电子设备,但实现具有手性交换相互作用的矢量变量仍是一个挑战。本文提出利用四分量变量,其参数耦合使天纹粒子得以稳定。有限元模拟表明,在由压电膜阵列组成的现实结构中存在声学天纹粒子。
英文摘要:
Skyrmions are topological solitons in two-dimensional systems and have been observed in various physical systems. Generating and controlling skyrmions in artificial resonator arrays lead to novel acoustic, photonic, and electric devices, but it is a challenge to implement a vector variable with the chiral exchange interaction. Here, we propose to use quadrature variables, where their parametric coupling enables skyrmions to be stabilized. A finite-element simulation indicates that a acoustic skyrmion would exist in a realistic structure consisting of a piezoelectric membrane array.
