一维长程Ising模型低温下的簇展开与关联衰减

A Cluster Expansion and the Decay of Correlations of the 1D Long-Range Ising Model at Low Temperatures

Rodrigo Bissacot, Henrique Corsini

AI总结:

针对多项式衰减指数α∈(1,2]的一维长程铁磁Ising模型,发展了收敛的低温簇展开,并证明两点关联函数以指数α代数衰减。

摘要:

本文针对具有多项式衰减$J(r)=r^{-α}$(其中$α\in (1,2]$)的一维长程铁磁Ising模型,发展了一种收敛的低温簇展开。作为应用,研究了$n$点关联函数,并证明两点关联函数以精确指数$α$代数衰减。

英文摘要:

In this work, a convergent low-temperature cluster expansion of the one-dimensional long-range ferromagnetic Ising model with polynomial decay $α\in (1,2]$ is developed; that is, $J(r)=r^{-α}$. As an application, the $n$-point correlations are studied and the two-point correlation is shown to be algebraic with rate of decay exactly $α$.
