摘要
应用实空间重整化群的方法,研究了一种分形上Ising模型的相变和临界性质,求出了系统的临界点0.264,根据RG理论,得到了系统的临界指数。与该分形上Gauss模型比较,系统的临界点和临界指数都发生了变化。
Using the renormalization-group transformation technique,the phase transition and critical properties of the Ising model on a type of fractal are studied,and its fixed point is obtained.According to RG theory,critical exponents are obtained.Compared with the Gauss model on the fractal,the critical point and critical exponents have changed.
