论文摘要
高温超导率包括铜层，镍，铁碎裂剂和lah $ _x $化合物。前三组化合物涉及配对电子，这些化合物与中等相关性，而在最后一类系统特定的声子激发中。在此概述中，我们首先将重点放在高t $ _ {C} $的（半）定量理论上，除了我们的原始振动方法之外，除了重新归一化的平均场理论之外，我们的原始振动方法。我们主要探索的模型主要是$ t $ - $ J $ - $ U $型号，其中既包含superexchange（动能），并结合了强大的互相关相关性。简要分析了选定的平衡和动态激发特性。有关这些系统的假单胞菌和二维特征的一般问题。
High temperature superconductivity encompasses the cuprates, nickelates, iron pnictides, and LaH$_x$ compounds. The first three groups of compounds involve in the pairing electrons, which are strongly to moderately correlated, whereas in the last class of systems specific phonon excitations. In this overview we concentrate first on the (semi)quantitative theory of high T$_{C}$ superconductivity in the cuprates based on our original vibrational approach beyond the renormalized mean field theory. The model we explore mainly is $t$-$J$-$U$ model containing both the superexchange (kinetic energy) combined with strong interelectronic correlations. Selected equilibrium and dynamic-excitation properties are analyzed briefly. General questions regarding the pseudogap and two--dimensional character of those systems are raised.
