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.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 ete. , it is hence natural to expect that the magnetic field can also affect these topolog- ical 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 circum- stance. Their relevant properties （ e. g. , the profile function and the tension energy） and the magnet- ic-field dependence are investigated with the Ginzburg-Landau framework.
