论文摘要
我们使用手性扰动理论构建了分析性（3+1） - 维度不均匀和拓扑非平凡的锥形系统。我们讨论了同种不对称的效果，即消失的电磁相互作用以及一些具有非消失电磁相互作用的特定构型。亲鼠场的不均匀构型的特征是非变化拓扑电荷，可以用被乳云云包围的重子识别。该系统支持拓扑保护的持续超级流。当电磁场打开时，超级流对应于电磁超流。
We construct analytic (3+1)-dimensional inhomogeneous and topologically non-trivial pion systems using chiral perturbation theory. We discuss the effect of isospin asymmetry with vanishing electromagnetic interactions as well as some particular configurations with non-vanishing electromagnetic interactions. The inhomogeneous configurations of the pion fields are characterized by a non-vanishing topological charge that can be identified with baryons surrounded by a cloud of pions. This system supports a topologically protected persistent superflow. When the electromagnetic field is turned on the superflow corresponds to an electromagnetic supercurrent.
