Abstract

We consider the gradient field model in [N,N]2Z2\left[ -N,N\right] ^{2}\cap \mathbb{Z}^{2} with a uniformly convex interaction potential. Naddaf-Spencer \cite{NS} and Miller \cite{Mi} proved that the macroscopic averages of linear statistics of the field converge to a continuum Gaussian free field. In this paper we prove the distribution of ϕ(0)/logN\phi(0)/\sqrt{\log N} converges uniformly to a Gaussian density, with a Berry-Esseen type bound. This implies the distribution of ϕ(0)\phi(0) is sufficiently `Gaussian like' between [logN,logN][-\sqrt {\log N}, \sqrt {\log N}].
