| 摘 要： | 本文介绍了蒙特卡罗方法的由来并简要地阐述了变分蒙特卡罗方法,给出了利用这种数值方法来处理超导理论中的t-J模型,讨论了在半满情况下t-J模型的能量基态,得到的数值结果支持A nderson所提出的RVB态就是或从某种程度上接近强关联系统的基态。

| Abstract: | In this article the method of variational Monte Carlo is briefly introduced and managed on t-J model for the case of half-filled.The calculated results support Anderson's suggestion that even for the half filled case,an RVB-type wave function might be the ground state or very close in energy to the ground state. |

| Keywords: | variational Monte Carlo strongly correlated system t-J model RVB |
