Abstract
We investigate the collision dynamics of two non-Abelian vortices and find that, unlike Abelian vortices, they neither reconnect themselves nor pass through each other, but create a rung between them in a topologically stable manner. Our predictions are verified using the model of the cyclic phase of a spin-2 spinor Bose-Einstein condensate.
摘要
我们研究了两个非阿贝尔涡旋的碰撞动力学，发现与阿贝尔涡旋不同，它们既不会重新连接，也不会相互穿过，而是以拓扑稳定的方式在它们之间形成一个梯级。我们的预测通过自旋 - 2旋量玻色 - 爱因斯坦凝聚体的循环相模型得到了验证。
