二维临界伊辛模型总能量的一个CLT

A CLT for the total energy of the two-dimensional critical Ising model

Jianping Jiang

摘要:

考虑临界温度下$([1,2N]\times[1,2M])\cap\mathbb{Z}^2$上的Ising模型,水平方向为周期边界条件,垂直方向为自由边界条件。令$E_{M,N}$为其总能量(或哈密顿量)。假设$M$是$N$的一个函数,对于某个$α\in[0,1)$满足$M\geq N/(\ln N)^α$。具体而言,可以服用$M=N$。我们证明了\begin{equation*} \frac{E_{M,N}+4\sqrt{2}M N-(4/π)N\ln N}{\sqrt{(32/π)MN\ln N}} \end{equation*}弱收敛于标准高斯分布为$N\rightarrow\infty$。

英文摘要:

Consider the Ising model on $([1,2N]\times[1,2M])\cap\mathbb{Z}^2$ at critical temperature with periodic boundary condition in the horizontal direction and free boundary condition in the vertical direction. Let $E_{M,N}$ be its total energy (or Hamiltonian). Suppose $M$ is a function of $N$ satisfying $M\geq N/(\ln N)^α$ for some $α\in[0,1)$. In particular, one may take $M=N$. We prove that \begin{equation*} \frac{E_{M,N}+4\sqrt{2}M N-(4/π)N\ln N}{\sqrt{(32/π)MN\ln N}} \end{equation*} converges weakly to a standard Gaussian distribution as $N\rightarrow\infty$.
