摘要翻译:
我们研究了具有[100]磁场的自旋冰材料的统计力学。我们证明了饱和磁化的方法在低温极限下是三维Kasteleyn跃迁的一个例子,它是拓扑的,即磁化只由横跨整个系统的激发来改变。我们用Monte Carlo聚类算法分析了这一转变,并将我们的结果与最近在Dy2Ti2O7上的实验数据进行了比较。

英文摘要:
We examine the statistical mechanics of spin-ice materials with a [100] magnetic field. We show that the approach to saturated magnetisation is, in the low-temperature limit, an example of a 3D Kasteleyn transition, which is topological in the sense that magnetisation is changed only by excitations that span the entire system. We study the transition analytically and using a Monte Carlo cluster algorithm, and compare our results with recent data from experiments on Dy2Ti2O7.
