大$N$标量模型的流动方程和诱导几何

Flow equation for the large $N$ scalar model and induced geometries

Sinya Aoki, Janos Balog, Tetsuya Onogi, Peter Weisz

摘要:

我们研究的建议,一个$d+1$维诱导度规构造从$d$维场论使用梯度流。将这一思想应用于O($N$)$φ^4$模型,并对流场进行归一化,我们在大的$N$极限下证明了诱导度规是有限的和普适的,因为它不依赖于流方程和原始场论的细节,除了重整化质量,它是这个极限下唯一相关的量。我们已经发现,诱导度规描述欧几里德Anti-de-Sitter(AdS)空间在紫外(UV)和红外(IR)限制的流动方向,其中的AdS的半径是在IR比在UV更大。

英文摘要:

We study the proposal that a $d+1$ dimensional induced metric is constructed from a $d$ dimensional field theory using gradient flow. Applying the idea to the O($N$) $φ^4$ model and normalizing the flow field, we have shown in the large $N$ limit that the induced metric is finite and universal in the sense that it does not depend on the details of the flow equation and the original field theory except for the renormalized mass, which is the only relevant quantity in this limit. We have found that the induced metric describes Euclidean Anti-de-Sitter (AdS) space in both ultra-violet (UV) and infra-red (IR) limits of the flow direction, where the radius of the AdS is bigger in the IR than in the UV.
