讨论了磁场沿立方[100]方向沿着分布的最近邻自旋冰模型。正如最近在Phys. Rev. Lett. 100,067207,2008中,在低温下观察到的对称性维持有序转变是三维Kasteleyn转变。我们确认这与数值数据使用非本地算法,保存在低温下的拓扑约束,并从分析计算从Bethe晶格的角共享四面体。我们提出了一个热力学描述的Kasteleyn过渡,并讨论我们的研究结果的相关性,最近的中子散射实验自旋冰材料。
We discuss the nearest neighbour spin ice model in the presence of a magnetic field placed along the cubic [100] direction. As recently shown in Phys. Rev. Lett. 100, 067207, 2008, the symmetry sustaining ordering transition observed at low temperature is a three dimensional Kasteleyn transition. We confirm this with numerical data using a non-local algorithm that conserves the topological constraints at low temperature and from analytic calculations from a Bethe lattice of corner sharing tetrahedra. We present a thermodynamic description of the Kasteleyn transition and discuss the relevance of our results to recent neutron scattering experiments on spin ice materials.
