The relation between center vortices and fractional topological charge has been studied in this work. Specifically, we investigate a vortex configuration with fractional topological charge analyzing the lowest modes of the adjoint Dirac operator in both overlap and staggered formulations. We discuss the effects leading to chiral symmetry breaking.

平面中心涡和分数拓扑电荷

本文研究了中心涡流与分数拓扑荷之间的关系。具体来说，我们研究了带有分数拓扑电荷的涡旋配置，分析了重叠和交错公式中伴随狄拉克算子的最低模式。我们讨论导致手征对称性破坏的影响。
