| 中文摘要 | with the variational cumulant expansion (vce) method, the thermodynamic behaviors of s = 1/2 antiferromagnetic heisenberg films in simple cubic lattices are studied analytically. from the analytic properties of the free energy, in principle we are able to calculate analytically the critical temperatures t-c(l) and the thermodynamic functions, to any order cumulant as the functions of the number of l (the hyperlayers in the hyperfilm). explicit expressions for t-c(l) up to the fourth order are given. a comparison with the existing results for 3-dimensional system is given. the effective range of the interaction is obtained from numerical results. |
