The ground state energy per unit cell,spin correlation function and staggered susceptibility are calculated.
利用密度矩阵重整化群(DMRG)方法研究一种S=1/2子格对称破缺的准一维反铁磁海森堡自旋链,计算了该系统单个原胞的基态能、自旋关联函数以及交错磁化率。
But for the 1/5-doped antiferromagntic chain,the quantum fluctuation leads to the 47% loss of its staggered susceptibility.
对于1/5掺杂反铁磁海森堡自旋链,量子涨落的影响明显,引起了交错磁化率47%的减弱。
