采用一种有效的簇团迭代法,对蜂窝状点阵量子Heisenberg反铁磁(QHAF)模型进行了MonteCarlo模拟.该方法避免了对于相应三维自旋模型迭代时出现的禁态和临界慢化效应.研究表明,该方法适用于普遍的具有A-B子格点阵的S=1/2反铁磁模型的研究.A new type of cluster algorithm is developed to simulate the two-dimensional spin one half quantum Heisenberg antiferromagnet (QHAF) on a hexagonal lattice. The numerical results show that the method can be applied to study efficiently the QHAF systems at lowertemperatures, with large Trotter number, on the general bipartite lattices.
