在渐近Bethe近似框架下，计算了具有变程交换的反铁磁量子自旋链基态的每格点能量。通过扩大它的权力，我们已经证实了第二个邻居相关的价值与最近邻交换模型早些时候在哈伯德链的原子极限。
We have calculated the energy per site for the ground state of the antiferromagnetic quantum spin chain with variable range exchange in the framework of the asymptotic Bethe ansatz. By expanding it in powers of , we have confirmed the value of the second-neighbour correlator for the model with nearest-neighbour exchange obtained earlier in the atomic limit of the Hubbard chain.
