讨论了在三态方波茨反铁磁体中引入的一种新型涡旋对相关衰变的作用。用蒙特卡罗方法测量了区域内涡旋电荷的波动。数据显示相关性呈指数衰减。在零温度下，考虑等效表面模型。蒙特卡罗实验表明，零温度波茨反铁磁体存在一种代数衰变。
The role of a new type of vortices introduced in the three-state squares Potts antiferromagnet for decay of correlations is considered. Fluctuations of the vortex charge in a region are measured using the Monte Carlo method. Data suggest an exponential decay of correlations. At zero temperature, an equivalent surface model is considered. A Monte Carlo experiment indicates roughening, thus suggesting an algebraical decay of the zero temperature Potts antiferromagnet.
