从红外缺陷重构 AdS 的边界

Reconstructing the boundary of AdS from an infrared defect

AI总结:

本文提出可由高维负曲率 Einstein 流形深处的余维二轨形缺陷重构低维渐近 AdS 边界,并猜想 $n\to\infty$ 时红外缺陷理论给出边界全息理论,且二维情形重现 Brown–Henneaux 中心荷。

摘要:

我们论证表明,一个 $d+1$ 维渐近 anti-de Sitter(AdS)空间(记为 $M^{d+1}$)的边界,可以从位于高一维负曲率 Einstein 流形 $X^{d+2}$ 深处内部的余维二缺陷进行局部重构。这意味着同一个 $d$ 维子流形 $\Sigma^d$ 存在两种不同的理解方式:它既可以看作嵌入 $X^{d+2}$ 内部的缺陷,也可以在某种零半径极限下视为 $M^{d+1}$ 的边界。基于这一思想以及其他几何和对称性论证,我们提出在体 $\mathbb Z_n$ 轨形缺陷上存在一种红外场论,该缺陷位于 AdS$^{d+2}$ 内部的最深处。我们进一步猜想,在轨形参数 $n\to\infty$ 的极限下,这一理论会产生 AdS$^{d+1}$ 渐近边界上的全息理论。作为示例,当 $\Sigma$ 是具有固定正曲率的二维流形时,我们计算了缺陷中心荷,并表明其 $n\to\infty$ 极限重现了 Brown 和 Henneaux 的中心荷。

英文摘要:

We argue that the boundary of an asymptotically anti-de Sitter (AdS) space of dimension $d+1$, say $M^{d+1}$, can be locally reconstructed from a codimension-two defect located in the deep interior of a negatively curved Einstein manifold $X^{d+2}$ of one higher dimension. This means that there exist two different ways of thinking about the same $d$-submanifold, $Σ^d$: either as a defect embedded in the interior of $X^{d+2}$, or as the boundary of $M^{d+1}$ in a certain zero radius limit. Based on this idea and other geometric and symmetry arguments, we propose the existence of an infrared field theory on a bulk $\mathbb Z_n$-orbifold defect, located in the deepest point of the interior of AdS$^{d+2}$. We further conjecture that such a theory gives rise to the holographic theory at the asymptotic boundary of AdS$^{d+1}$, in the limit where the orbifold parameter $n\to\infty$. As an example, we compute a defect central charge when $Σ$ is a 2-manifold of fixed positive curvature, and show that its $n\to\infty$ limit reproduces the central charge of Brown and Henneaux.
