论文摘要
我们表明，磁性材料中可能存在非亚伯涡流。这些是无奇异的纹理，用自旋晶格和场理论模型来描述，我们证明典型的磁性材料非常适合其实现和观察。我们对这些涡旋进行了拓扑分类，并揭示了它们与Abelian拓扑结构的联系，例如通常的涡流，Merons和Skyrmions。我们还描述了与阿贝尔实体相比，非亚伯磁性涡流如何携带受拓扑保护的信息，并提出了使此类信息载体优势的原因。
We show that non-Abelian vortices can exist in magnetic materials. These are singularity-free textures, are described by spin-lattice and field theory models, and we demonstrate that typical magnetic materials can be quite suitable for their realization and observation. We give a topological classification of these vortices and reveal their connection with Abelian topological structures, such as usual vortices, merons and skyrmions. We also describe how non-Abelian magnetic vortices can carry topologically protected information and present reasons for the advantage of such information carriers, as compared to Abelian entities.
