论文摘要
我们使用全息图来研究由$（P，Q）$ 5 Brane网设计的5D SCFTS中的Codimension-2表面缺陷。三维缺陷是通过在Brane Web上结尾的D3烧烤来实现的。我们将IIB $ ADS_6 $ solutions中缺陷的全息表示为探针D3-溴，并研究了保形和非统一缺陷，分别保留了超对称性的一半和四分之一。对于包括$ T_N $理论在内的5D SCFT的样本，我们为共形和非统一缺陷提供明确的解决方案。对于保形缺陷，我们在$ s^5 $上获得了他们对自由能的贡献。
We use holography to study codimension-2 surface defects in 5d SCFTs engineered by $(p,q)$ 5-brane webs. The three-dimensional defects are realized by D3-branes ending on the brane web. We identify the holographic representation of the defects in Type IIB $AdS_6$ solutions as probe D3-branes, and study conformal and non-conformal defects which, respectively, preserve one half and one quarter of the supersymmetry. For a sample of 5d SCFTs, including the $T_N$ theories, we provide explicit solutions for conformal and non-conformal defects. For the conformal defects we obtain their contribution to the free energy on $S^5$.
