摘要
本文使用严格的实空间重整化群方法研究了自相似结构 Sierpinski Carpet 的动力学标度行为,求得谱维度 ds=1.611,参考电导指数 t 的数值计算结果,我们通过爱因斯坦关系验证发现所求谱维度结果较好,并且我们求得了零温下各向同性海森堡自旋系统的动力学指数 Z。
By an exact real space renormalization group method,the scaling behavior of Sierpinsk_1 Carpet is studied and the spectral dimension is obtained as ds=1.611.The result is checked with the numerical caculation of DC con- ductivity exponent t in the Einstein relation.Besides,The dynamic exponent Z for heisenberg spin system at percolation threshold also caculated.
