Flow equation for the large N scalar model and induced geometries

アブストラクト：

We study the proposal that a $d+1$ dimensional induced metric is constructed from a $d$ dimensional field theory using the gradient flow.
Applying the idea to the O(N) $\varphi^4$ 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 detail of the flow equation and the original field theory except the renormalized mass, which is only a relevant quantity in this limit.
We have found that the induced metric describes the Euclidean Anti-de-Sitter (AdS) space in both ultra-violate (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.
