摘要
用Zou-Anderson有效哈密顿量计算了spinon-holon系统的动态横向磁化率。由讨论holon涨落效应,导出一铁磁相互作用,这一相互作用对解释Hubbard模型的铁磁相变有重要的意义。
The spinon-holon effective Hamiltonian proposed by Zou and Anderson isused to calculate the dynamic susceptibility. By considering holon flucluationseffect We derive a ferromagnetie interaction which is fundamental important forgain a ferromagnetic phase with our RPA scheme.
