我们描述了在规范对称性完全破缺的相中包含磁单极子的Yang-Mills-Higgs理论的新解。磁力线形成磁通管，而不是径向展开。该溶液是拓扑稳定的，当嵌入N=2SQCD时，保留了1/4的超电荷。从通量管的角度来看，单极子看起来像一个扭结。许多单极子可以穿在单一的通量管上，并以任意的间隔放置，以产生稳定的BPS孤子项链。
We describe new solutions of Yang-Mills-Higgs theories consisting of magnetic monopoles in a phase with fully broken gauge symmetry. Rather than spreading out radially, the magnetic field lines form flux tubes. The solution is topologically stable and, when embedded in N = 2 SQCD, preserves 1/4 of the supercharges. From the perspective of the flux-tube the monopole appears as a kink. Many monopoles may be threaded onto a single flux tube and placed at arbitrary separation to create a stable, BPS necklace of solitons.
