使用蒙特卡罗技术，研究了具有铁磁最近邻相互作用和表面自旋之间增强耦合的伊辛立方体。特别是，在表面转变时，角磁化在热力学极限下表现出非普遍的、依赖于耦合的临界行为。将角磁化强度临界指数的结果与先前对具有三个相交缺陷线的二维 Ising 模型的研究结果进行了比较。
Using Monte Carlo techniques, Ising cubes with ferromagnetic nearest-neighbor interactions and enhanced couplings between surface spins are studied. In particular, at the surface transition, the corner magnetization shows nonuniversal, coupling-dependent critical behavior in the thermodynamic limit. Results on the critical exponent of the corner magnetization are compared to previous findings on two-dimensional Ising models with three intersecting defect lines.
