AI 中文摘要
我简要概述了从 Hubbard 模型出发的 t-J 模型的原始表述，并强调其在讨论物理性质时的独特特征，即优点和缺点。特别强调了磁性、非常规超导性与窄带中关联载流子的 Mott-Hubbard 局域化之间联系的简要描述。在第二部分，我总结了模型向三轨道情形的推广。主要目的是列出与 t-J 模型相关的物理的一些基本特征。
英文摘要
I briefly overview the original formulation of the t-J model starting from Hubbard model, as well as stress its unique features, i.e., advantages and shortcomings when discussing its physical properties. Particular emphasis is put on a brief characterization of connection between magnetism, unconventional superconductivity, and the Mott-Hubbard localization of the correlated carriers in a narrow band. In the second part I summarize the model generalization to the three--orbital situation. The main purpose is to list some basic features of the physics associated with t--J model.
