摘要: |
最近的研究表明强磁场对强相互作用物质,特别是稠密夸克物质的色味连锁相,会产生非常重要的影响.稠密夸克物质提供诸如涡旋,畴壁,单极子,扭结,布胶(boojum)等各种拓扑孤立子,因此可以预期强磁场也应该会影响这些孤立子.在这篇小综述中,介绍了在色味连锁夸克物质磁场效应研究的最新进展, 特别是特定条件下最基础的类弦拓扑激发非阿贝尔涡旋.在金兹堡-朗道框架下研究了它们的相关性质(如轮廓函数和张力能)以及磁场依赖性. |

Abstract: |
It is recently known that strong magnetic fields may lead to highly nontrivial effects on strongly interacting matter,including the color-flavor-locked phase of dense quark matter.Dense quark matter provides various kind of topological solitons such as vortices,domain walls,monopoles,kinks,boojums etc.,it is hence natural to expect that the magnetic field can also affect these topological solitons.In this mini-review,we update our recent progress on the studies of magnetic field effects in the color-flavor-locked quark matter.The particular emphasis is given on the non-Abelian vortices since they are the most fundamental string-like topological excitations under certain circumstance.Their relevant properties (e.g.,the profile function and the tension energy) and the magnetic-field dependence are investigated with the Ginzburg-Landau framework. |
