弯曲空间上大质量缺陷的超对称D3/D5

Supersymmetric D3/D5 for massive defects on curved space

Brandon Robinson, Christoph F. Uhlemann

摘要:

我们构造了$\mathcal N=4$ SYM在$\rm S^4$和$\rm AdS_4$上的全息对偶,它们耦合到余维1缺陷上的大质量$\mathcal N=2$超对称淬灭味场,分别是$\rm S^3$和$\rm AdS_3$。全息描述是根据D3/探针D5膜系统进行的。建立并约化了具有任意超对称形变的D5-膜嵌入的BPS方程,并在非线性水平上部分求解。其余的方程在小质量展开中显式求解。我们计算了缺陷场对S $^4$配分函数的贡献,并与使用超对称局域化的场论计算进行了比较,为此我们建立了矩阵模型。这两个计算同意,贷款强有力的支持全息探测膜建设使用D3/D5配置一般。

英文摘要:

We construct the holographic dual for $\mathcal N=4$ SYM on $\rm S^4$ and $\rm AdS_4$ coupled to massive $\mathcal N=2$ supersymmetric quenched flavor fields on a codimension-1 defect, which is $\rm S^3$ and $\rm AdS_3$, respectively. The holographic description is in terms of a D3/probe D5 brane system. We set up and reduce the BPS equations for D5-brane embeddings with arbitrary supersymmetric deformations and partly solve them at the non-linear level. The remaining equations are solved explicitly in a small-mass expansion. We compute the contribution of the defect fields to the partition function on S$^4$ and compare to a field theory computation using supersymmetric localization, for which we set up the matrix model. Both computations agree, lending strong support to holographic probe brane constructions using D3/D5 configurations in general.
