论文摘要
我们通过在脱钩限制中扰动$ n $ umaryal d3-branes的两个堆栈，在IIB型超级型中构建一个单边界虫洞几何形状。溶液通过中间区域的谐波两中心溶液从内部的双面平面ADS-SCHWARZSCHILD几何形状插值，到渐近ADS空间。该结构涉及虫洞粘合到外部喉咙的CPT扭曲，从而为某些坐标提供了全球单形状，同时可以保持可赋。几何形状以$ \ nathcal {n} = 4 $ $ $ su（2n）$ super yang-mills理论的双重解释，就higgsed $ su（2n）\ to s（u（u（n）\ times u（times u（n）\ times u（t）在温度下的双状态比希格斯量表要冷得得多。我们认为该解决方案可以通过适当的选择参数进行长期寿命，并评论产生遍历性的机制。我们还描述了两个宇宙之间双虫洞的结构。
We construct a single-boundary wormhole geometry in type IIB supergravity by perturbing two stacks of $N$ extremal D3-branes in the decoupling limit. The solution interpolates from a two-sided planar AdS-Schwarzschild geometry in the interior, through a harmonic two-center solution in the intermediate region, to an asymptotic AdS space. The construction involves a CPT twist in the gluing of the wormhole to the exterior throats that gives a global monodromy to some coordinates, while preserving orientability. The geometry has a dual interpretation in $\mathcal{N}=4$ $SU(2N)$ Super Yang-Mills theory in terms of a Higgsed $SU(2N) \to S(U(N) \times U(N))$ theory in which $\mathcal{O} (N^2)$ degrees of freedom in each $SU(N)$ sector are entangled in an approximate thermofield double state at a temperature much colder than the Higgs scale. We argue that the solution can be made long-lived by appropriate choice of parameters, and comment on mechanisms for generating traversability. We also describe a construction of a double wormhole between two universes.
