论文摘要
我们使用Tensor Rentarization Grout thriaD近似值研究了在热力学极限下的立方晶格上的$ Q $ - 状态POTTS模型。通过计算热力学电势,我们以$ 10 <q \ le 20 $的价格找到一阶相变,该转换尚未使用任何方法探索。我们还研究了三合会近似方法在获取固定点张量的效率,并评论如何改善这一点。
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.
