AI总结:

本文研究了$d=4$ SCFT中对偶于IIB型超引力解的二维超共形缺陷,计算了$\mathcal{N}=4$ SYM和Leigh-Strassler SCFT中缺陷的中心荷、在壳作用和Rényi熵,并证明了两者的缺陷通过质量形变和RG流相关联。

摘要:

我们研究了IIB型超引力解,这些解对偶于$d=4$ SCFT中保持$\mathcal{N}=(0,2)$超对称性的二维超共形缺陷。我们考虑了对偶于$\mathcal{N}=4$ SYM理论中缺陷的解,这些缺陷对于$U(1)^3\subset SO(6)$全局对称性具有非平庸单值,并且我们也允许圆锥奇点的可能性。此外,我们考虑了添加费米子和玻色子质量项,这些质量项对垂直于缺陷的空间方向具有非平庸的依赖关系,同时保持缺陷的超共形对称性。我们计算了各种物理量,包括表示为单值函数的缺陷中心荷、在壳作用以及相关的超对称Rényi熵。对于$\mathcal{N}=1$,$d=4$ Leigh-Strassler SCFT中的超共形缺陷,我们也进行了类似的计算。我们还证明了这两个SCFT的缺陷通过一条体边缘质量形变线相连,并论证了它们也可以通过体RG流相关联。

英文摘要:

We study type IIB supergravity solutions that are dual to two-dimensional superconformal defects in $d=4$ SCFTs which preserve $\mathcal{N}=(0,2)$ supersymmetry. We consider solutions dual to defects in $\mathcal{N}=4$ SYM theory that have non-trivial monodromy for $U(1)^3\subset SO(6)$ global symmetry and we also allow for the possibility of conical singularities. In addition, we consider the addition of fermionic and bosonic mass terms that have non trivial dependence on the spatial directions transverse to the defect, while preserving the superconformal symmetry of the defect. We compute various physical quantities including the central charges of the defect expressed as a function of the monodromy, the on-shell action as well as associated supersymmetric Renyi entropies. Analogous computations are carried out for superconformal defects in the $\mathcal{N}=1$, $d=4$ Leigh-Strassler SCFT. We also show that the defects of the two SCFTs are connected by a line of bulk marginal mass deformations and argue that they are also related by bulk RG flow.
