具有畴壁边界条件的 Ising 模型的自旋簇边界的标度极限是 κ = 3 的 Schramm–Loewner 演化 (SLE)。我们假设具有适当边界条件的三态 Potts 模型具有在标度极限下也是 SLE 的自旋簇边界,但 κ = 10/3。为了测试这一点,我们使用 Wolff 算法生成样本,并根据 SLE 的预测对其进行测试:我们检查 Loewner 驱动函数的统计数据,估计分形维数并根据 Schramm 公式进行测试。结果支持了我们的假设。
The scaling limit of the spin cluster boundaries of the Ising model with domain wall boundary conditions is Schramm–Loewner evolution (SLE) with κ = 3. We hypothesize that the three-state Potts model with appropriate boundary conditions has spin cluster boundaries which are also SLE in the scaling limit, but with κ = 10/3. To test this, we generate samples using the Wolff algorithm and test them against predictions of SLE: we examine the statistics of the Loewner driving function, estimate the fractal dimension and test against Schramm’s formula. The results are in support of our hypothesis.
