Classification of magnetic vortices by angular momentum conservation
Superfluid vortices are quantum excitations carrying a quantized amount of orbital angular momentum in a phase where global symmetry is spontaneously broken. We address a question whether magnetic vortices in superconductors with dynamical gauge fields carry nonzero orbital angular momentum or not....

| description | Superfluid vortices are quantum excitations carrying a quantized amount of orbital angular momentum in a phase where global symmetry is spontaneously broken. We address a question whether magnetic vortices in superconductors with dynamical gauge fields carry nonzero orbital angular momentum or not. We provide the answer in view of the angular momentum conservation in several distinct classes of examples from interdisciplinary fields of physics across condensed matter, dense nuclear systems, and cosmology. The angular momentum carried by gauge field configuration around the magnetic vortex plays a crucial role in satisfying the principle of the angular momentum conservation. Based on various ways on how the angular momentum conservation is realized, we provide a general scheme of classifying magnetic vortices in different phases of matter. |
