用变分法导出了自旋XY磁体基态的近似波函数。该波函数对基态能量和长程阶的估计与Betts和Oitmaa用有限点阵法得到的结果非常吻合。
An approximate wave function of the ground state of the spin XY magnet is derived using a variational method. This wave function yields estimates of the ground state energy and long-range order which agree very well with the results obtained by Betts and Oitmaa by a finite lattice method.
