论文摘要
我们根据量规/重力二元性和ADS Swampland猜想来回顾S折研究的最新进展。 s折对应于表格$ \，\ textrm {ads} _4 \，\ times \，\ textrm {s}^1 \，\ times \，\ times \，\ nathcal {mathcal {m} \，$ thit涉及非trivialial的非几何背景$ \，\ textrm {sl}（2，\，\，\ Mathbb {z}）\，$（s-duality）type iib字段的monodity在$ \，\ textrm {s}}^1 $时移动时。我们通过$ \，\ Mathcal {m} = \ textrm {s}^{5} \，$介绍了四个这样的解决方案，可以保留$ \，\ Mathcal {n} = 4,2,1,0 \，$ supersymmetries。通过AD/CFT对应关系，这些解决方案被猜想以描述SYM局部界面上的新的强耦合三维CFT。我们讨论了重力侧双重形式的平坦变形，以指出S折CFT的边缘变形。从几何学的角度来看，平面变形会引起$ \，\ \ \ nathcal {m} \，$ in $ \，$，$和$ \，$和$ \，\ textrm {s}^1 \，\ times \ times \ times \，\ time $ \，t（\ Mathcal {M}）_ H $。有趣的是，扁平变形提供了$ \，\ Mathcal {n} \ ge 2 \，$ s折的超对称性破坏的控制机制。我们提出了通过扁平化$ \，\ MATHCAL {n} = 4 \，$ s折叠并讨论其（非 - 非扰动稳定性）获得的一类这种非苏匹配S折。
We review recent progress in the study of S-folds in light of the gauge/gravity duality and the AdS swampland conjecture. S-folds correspond to non-geometric backgrounds of type IIB supergravity of the form $\,\textrm{AdS}_4 \, \times \, \textrm{S}^1 \, \times \, \mathcal{M}\,$ that involve a non-trivial $\,\textrm{SL}(2,\,\mathbb{Z})\,$ (S-duality) monodromy for the type IIB fields when moving around the $\,\textrm{S}^1$. We present four such solutions with $\,\mathcal{M}=\textrm{S}^{5}\,$ that preserve $\,\mathcal{N}=4,2,1,0\,$ supersymmetries. Via the AdS/CFT correspondence, these solutions are conjectured to describe new strongly coupled three-dimensional CFT's on a localised interface of SYM. We discuss the existence of flat deformations in the gravity side dual to marginal deformations of the conjectured S-fold CFT's. From a geometrical perspective, the flat deformations induce a monodromy $\,h\,$ on $\,\mathcal{M}\,$ and replace $\,\textrm{S}^1 \,\times\, \mathcal{M}\,$ by the so-called mapping torus $\,T(\mathcal{M})_h$. Interestingly, the flat deformations provide a controlled mechanism of supersymmetry breaking for $\,\mathcal{N} \ge 2\,$ S-folds. We present a class of such non-supersymmetric S-folds obtained by flat-deforming the $\,\mathcal{N}=4\,$ S-fold and discuss their (non-)perturbative stability.
