二维随机三角点阵上三态和四态Potts模型的蒙特—卡罗重整化群研究

MONTE CARLO RENORMALIZATION GROUP STUDY OF THREE-STATE AND FOUR-STATE POTTS MODEL ON TWO-DIMENSIONAL RANDOM TRIANGLE LATTICE

本文用改进的蒙特-卡罗重整化群方法对二维随机三角点阵上的三态和四态Potts模型进行研究,分析它们的固定点及临界指数,所得的临界指数与理论的分析值符合很好。

An improved Monte Carlo renormalization group method is applied to three-state and four-state Potts models on two-dimensional random triangle lattice. Their fixed points and critical exponents are analysed. The critical exponents obtained are consistent with the theoretical analytical values.
