如hep-th/9709081所示，非BPS饱和孤子在N=1超对称规范理论的对偶变换中发挥着重要作用。特别是，在矢量表示中具有无质量物质的 SO(N) 规范理论中的大质量旋量在对偶描述中显示为具有 Z_2 电荷的磁单极子。这一说法得到了众多测试的支持，包括风味量子数的详细匹配。这一事实使得使用大质量旋量作为探针来测试 SO(N) 规范理论的相位成为可能。由此明确表明，超对称理论中出现的自由磁相是非约束相。还展示了双迈斯纳效应的完全非阿贝尔版本，其中单极子受到带有 Z_2 电荷的非 BPS 弦孤子的限制。
As shown in hep-th/9709081, non-BPS saturated solitons play an important role in the duality transformations of N=1 supersymmetric gauge theories. In particular, a massive spinor in an SO(N) gauge theory with massless matter in the vector representation appears in the dual description as a magnetic monopole with a Z_2 charge. This claim is supported by numerous tests, including detailed matching of flavor quantum numbers. This fact makes it possible to test the phase of an SO(N) gauge theory using massive spinors as a probe. It is thereby shown explicitly that the free magnetic phase which appears in supersymmetric theories is a non-confining phase. A fully non-abelian version of the Dual Meissner effect is also exhibited, in which the monopoles are confined by non-BPS string solitons with Z_2 charges.
