摘要

本文回顾了哈伯德模型的最新研究成果。在mott跃迁区发生的是Mott-Hubbard隙内Gutzwiller重电子带的形成,以及通过交换相互作用导致的重电子液体的磁性或超导不稳定性。介绍了铜氧化物在高温超导中的应用。

Heavy Electrons in the Mott-Transition Region
Recent work on the Hubbard model is reviewed. What occur in the Mott-transition region are the formation of the Gutzwiller heavy-electron band within the Mott-Hubbard gap, and magnetic or superconducting instability of heavy-electron liquids by exchange interac­ tions. Application to high-temperature superconductivity in the cuprate oxides is presented ..
