$\mathcal{N}=2$超对称S-折叠

$\mathcal{N}=2$ supersymmetric S-folds

Adolfo Guarino, Colin Sterckx, Mario Trigiante

摘要:

在$\,\mathbb{R} \times \textrm{S}^5\,$上约化IIB型超引力所产生的$\,[\textrm{SO}(1,1) \times \textrm{SO}(6)] \ltimes \mathbb{R}^{12}\,$最大超引力中发现了具有不同超对称性和剩余规范对称性的AdS $_{4}$真空的多参数族。这些提供了自然的候选人全息描述新的强耦合的三维CFT的本地化的界面上的$\,\mathcal{N}=4\,$超杨-米尔斯理论。一个这样的AdS $_{4}$真空的特征是对称性增强到$\,\textrm{SU}(2) \times \textrm{U}(1)\,$,同时保持$\,\mathcal{N}=2\,$超对称性。利用$\,\textrm{E}_{7(7)}\,$例外场论的提取技术,将其提升为一类IIB型超引力$\,\mathcal{N}=2\,$ S-褶皱,其形式为$\,\textrm{AdS}_{4} \times \textrm{S}^{1} \times \textrm{S}^5\,$,包含沿$\,\textrm{S}^{1}\,$的双曲型S-对偶扭转。

英文摘要:

Multi-parametric families of AdS$_{4}$ vacua with various amounts of supersymmetry and residual gauge symmetry are found in the $\,[\textrm{SO}(1,1) \times \textrm{SO}(6)] \ltimes \mathbb{R}^{12}\,$ maximal supergravity that arises from the reduction of type IIB supergravity on $\,\mathbb{R} \times \textrm{S}^5\,$. These provide natural candidates to holographically describe new strongly coupled three-dimensional CFT's which are localised on interfaces of $\,\mathcal{N}=4\,$ super-Yang--Mills theory. One such AdS$_{4}$ vacua features a symmetry enhancement to $\,\textrm{SU}(2) \times \textrm{U}(1)\,$ while preserving $\,\mathcal{N}=2\,$ supersymmetry. Fetching techniques from the $\,\textrm{E}_{7(7)}\,$ exceptional field theory, its uplift to a class of $\,\mathcal{N}=2\,$ S-folds of type IIB supergravity of the form $\,\textrm{AdS}_{4} \times \textrm{S}^{1} \times \textrm{S}^5\,$ involving S-duality twists of hyperbolic type along $\,\textrm{S}^{1}\,$ is presented.
