我们介绍了在（随机）场存在下的三维爱德华兹 - 安德森自旋玻璃的蒙特卡洛模拟的结果。相关长度的有限尺寸缩放分析与零场的情况相反，没有表明过渡的迹象。这表明没有Almeida-thou thou thou thou thou thouless用于短程式旋转眼镜。
We present results of Monte Carlo simulations of the three-dimensional Edwards-Anderson Ising spin glass in the presence of a (random) field. A finite-size scaling analysis of the correlation length shows no indication of a transition, in contrast with the zero-field case. This suggests that there is no Almeida-Thouless line for short-range Ising spin glasses.
