三维Potts模型的张量重整化

Tensor renormalization of three-dimensional Potts model

Raghav G. Jha

摘要:

在三元组近似下,利用张量重整化群变换研究了热力学极限下立方晶格上的$q$态Potts模型.通过计算热力学势,我们确定了$10 < q \le 20$的一级相变位置。我们还研究了三重近似方法在获得固定点张量的效率,并评论如何可以提高。

英文摘要:

We study the $q$-state Potts models on a cubic lattice in the thermodynamic limit using tensor renormalization group transformations with the triad approximation. By computing the thermodynamic potentials, we locate the first-order phase transitions for $10 < q \le 20$ which has not been explored using any method. We also examine the efficiency of the triad approximation method in obtaining the fixed-point tensor and comment on how this can be improved.
