论文摘要
超流体涡旋是量子激发，在自发损坏的整体对称性的相位中，载有量化数量的轨道角动量。我们解决了一个问题，即具有动力学轨迹场的超导体中的磁涡旋是否可以携带非零轨道角动量。我们讨论了来自凝结物物质，密集的核系统和宇宙学的几个不同类别的实例中的角动量保护。轨距场构型携带的角动量周围磁性涡流在满足保护定律的原理中起着至关重要的作用。根据各种方式实现角动量保护的方式，我们提供了一种在物质不同阶段对磁涡质进行分类的一般方案。
Superfluid vortices are quantum excitations carrying quantized amount of orbital angular momentum in a phase where global symmetry is spontaneously broken. We address a question of whether magnetic vortices in superconductors with dynamical gauge fields can carry nonzero orbital angular momentum or not. We discuss the angular momentum conservation in several distinct classes of examples from crossdisciplinary fields of physics across condensed matter, dense nuclear systems, and cosmology. The angular momentum carried by gauge field configurations around the magnetic vortex plays a crucial role in satisfying the principle of the conservation law. Based on various ways how the angular momentum conservation is realized, we provide a general scheme of classifying magnetic vortices in different phases of matter.
