| 摘 要： | 关于二维伊辛模型的严格解,传统上多采用转移矩阵方法,过程较为繁杂.应用格拉斯曼路径积分方法求解在一系列晶格上的二维伊辛模型的严格解.利用格拉斯曼变量的代数简化求和的计算,把自旋耦合求和变成自旋平均计算,在这方面使得求解的过程较传统方法简化许多.

| Abstract: | The exact solution with Respect to two-dimensional Ising modle mostly use transfer matrix traditionally, the solving process is rather miscellaneous. The exact solution of two-dimensional Ising modle are obtained by using Grassmann path integral. So the sum of spinor can be simply replaced by the spin average calculation by using grassmann variables algebraic simplified sum spin coupling sum and reduce the computational complexity. |
