将有限元标度方法应用于一维扩展Hubbard哈密顿量。关联函数的结果表明，在半充满带的情况下，跳跃混合了电荷有序态和自旋有序态。与实空间重整化群方法一样，我们发现这些态之间的跃迁是连续的，并且在跃迁附近，系统处于电荷有序自旋有序混合态。
The finite-cell scaling method is applied to the one-dimensional extended Hubbard Hamiltonian. The results obtained for the correlation functions show that, in the half-filled-band case, the hopping mixes the charge-ordered and the spin-ordered states. As with the real-space renormalization-group method, we find that the transition between these states is continuous and that the system, in the vicinity of the transition, is in a mixed charge-ordered—spin-ordered state.
