论文摘要
使用物理直觉的Migdal-Kadanoff Renormalization-Group-Group-Group-Group-Group-Group-Group-Group-Group-Group转换的简单适应，在q-State Potts模型中从Q-State Potts模型中的一阶变为二阶相变的转换。这种简单的过程在一阶相变时产生潜热。在d = 2和3中，与确切的自偶性和蒙特卡洛结果相比，计算出的相变温度分别得到了显着改善。
The changeover from first-order to second-order phase transitions in q-state Potts models is obtained at q_c=2 in spatial dimension d=3 and essentially at q_c=4 in d=2, using a physically intuited simple adaptation of the Migdal-Kadanoff renormalization-group transformation. This simple procedure yields the latent heats at the first-order phase transitions. In both d=2 and 3, the calculated phase transition temperatures, respectively compared with the exact self-duality and Monte Carlo results, are dramatically improved.
