摘要：

本文用数值方法构造了2+1维SU（2）Chern-Simons-Higgs理论的非阿贝尔涡旋。它们代表了Hong、Kim和Pac以及Jackiw和Weinberg所考虑的U（1）解的自然对应物。阿贝尔嵌入确定，所有的希格斯自相互作用强度值$ν$，导致在吸引和排斥阶段。对解的性质的详细分析揭示了一些意想不到的特征的存在。结果表明，在一定的$ν$参数范围内，非阿贝尔涡旋的能量比拓扑稳定的阿贝尔涡旋的能量低，从而导致SU（2）组态的有效能量下界.对这些涡旋的角动量进行了分析，发现与角动量和能量无关的阿贝尔涡旋不同，非阿贝尔涡旋具有非平凡的质量-自旋关系。

英文摘要：

Non Abelian vortices of a SU(2) Chern-Simons--Higgs theory in 2+1 dimensions are constructed numerically. They represent natural counterparts of the U(1) solutions considered by Hong, Kim and Pac, and, by Jackiw and Weinberg. The Abelian embeddings are identified, for all values of the Higgs selfinteraction strength $ν$, resulting in both attractive and repulsive phases. A detailed analysis of the properties of the solutions reveals the existence ofa number of unexpected features. For a certain range of the parameter $ν$, it is shown that the non Abelian vortices have lower energy than their topologically stable Abelian counterparts, resulting in an effective energy lower bound on the SU(2) configurations. The angular momentum of these vortices is analysed and it is found that unlike the Abelian ones, whose angular momentum and energy are unrelated, there is a nontrivial mass--spin relation of the non Abelian vortices.
