空间非均匀CP-奇域中电磁场的自发拓扑跃迁

Spontaneous topological transitions of electromagnetic fields in spatially inhomogeneous CP-odd domains

Kirill Tuchin

摘要:

热QCD物质的亚稳CP奇畴通过手征反常耦合到QED。这些磁畴中的电磁场拓扑结构具有磁螺旋性的特征。利用Maxwell-Chern-Simons模型,我们认为磁畴的空间不均匀性会导致电磁场在相反的磁螺旋态之间的自发跃迁。

英文摘要:

Metastable CP-odd domains of the hot QCD matter are coupled to QED via the chiral anomaly. The topology of electromagnetic field in these domains is characterized by magnetic helicity. It is argued, using the Maxwell-Chern-Simons model, that spatial inhomogeneity of the domains induces spontaneous transitions of electromagnetic field between the opposite magnetic helicity states.
