论文摘要
在存在二次缺陷的情况下，我们考虑了四个维度的自由麦克斯韦场。在这种情况下，反射正面的两个缺陷，在这种情况下保留共形对称性。我们显示只有广义的自由场才能出现在散装麦克斯韦场的缺陷操作员产品扩展中。这些缺陷操作员的特别相关函数可以通过Wick定理评估。
We consider a free Maxwell field in four dimensions in the presence of a codimension two defect. Reflection positive, codimension two defects which preserve conformal symmetry in this context are very limited. We show only generalized free fields can appear in the defect operator product expansion of the bulk Maxwell field; in particular correlation functions of these defect operators can be evaluated via Wick's Theorem.
