论文摘要
我们在IIB型字符串理论实现Braneworld模型中开发了双全息图的概念。 IIB类型的设置基于4D BCFT的全息二，包括4D $ \ MATHCAL N = 4 $ SYM在半空间上，与3D $ \ MATHCAL N = 4 $ scfts耦合到边界上。基于混凝土BCFT及其勃起构造，我们提供了中间全息描述的微观实现，该描述仅通过对3D自由度进行偶联而获得。在自下而上模型中的最新观察结果触发的情况下，我们讨论了完整的BCFT对偶和中间描述中的因果结构。这证实了自下而上模型中发现的定性特征，但提出了对其解释的改进。
We develop the notion of double holography in Type IIB string theory realizations of braneworld models. The Type IIB setups are based on the holographic duals of 4d BCFTs comprising 4d $\mathcal N=4$ SYM on a half space coupled to 3d $\mathcal N=4$ SCFTs on the boundary. Based on the concrete BCFTs and their brane construction, we provide microscopic realizations of the intermediate holographic description, obtained by dualizing only the 3d degrees of freedom. Triggered by recent observations in bottom-up models, we discuss the causal structures in the full BCFT duals and intermediate descriptions. This confirms qualitative features found in the bottom-up models but suggests a refinement of their interpretation.
