非阿贝尔涡旋是稠密QCD色香味锁相中的拓扑稳定对象。我们从色味锁相的Ginzburg-Landau有效拉格朗日量出发，导出了一个对偶拉格朗日量，并得到了非阿贝尔涡旋与Nambu-Goldstone玻色子（声子）和大质量胶子等准粒子的拓扑相互作用.我们发现声子耦合到涡旋的平移零模，而胶子耦合到内部空间的取向零模。
Non-Abelian vortices are topologically stable objects in the color-flavor locked phase of dense QCD. We derive a dual Lagrangian starting with the Ginzburg-Landau effective Lagrangian for the color-flavor locked phase, and obtain topological interactions of non-Abelian vortices with quasiparticles such asNambu-Goldstone bosons (phonons) and massive gluons. We find that the phonons couple to the translational zero modes of the vortices while the gluons couple to their orientational zero modes in the internal space.
