论文摘要
我们回顾了强相关电子的SU（4）模型在基于铁和铁的超导体中的应用。 BCS理论的最小自洽概括在与配对和强烈的库仑排斥相等的基础上结合了抗势力磁性，可以系统地考虑到高温超导性的主要特征，并具有仅输入参数参数的父级化合物的显微镜细节。这提供了一个系统的程序，可以将必需品与外围分开，这表明高$ t \ tsub c $数据集所展示的许多功能本身就是感兴趣的，但对超导机制并不核心。更普遍地，我们建议，在许多物理领域中观察到的一系列常规和非常规的超导和超流体行为是由于新兴有效的汉密尔顿人的相似代数结构的系统出现，即使相应父母的微观汉密尔顿人的相似有效的汉密尔顿人的系统出现可能与彼此的相应父母的微观汉密尔顿可能不同。
We review application of the SU(4) model of strongly-correlated electrons to cuprate and iron-based superconductors. A minimal self-consistent generalization of BCS theory to incorporate antiferromagnetism on an equal footing with pairing and strong Coulomb repulsion is found to account systematically for the major features of high-temperature superconductivity, with microscopic details of the parent compounds entering only parametrically. This provides a systematic procedure to separate essential from peripheral, suggesting that many features exhibited by the high-$T\tsub c$ data set are of interest in their own right but are not central to the superconducting mechanism. More generally, we propose that the surprisingly broad range of conventional and unconventional superconducting and superfluid behavior observed across many fields of physics results from the systematic appearance of similar algebraic structures for the emergent effective Hamiltonians, even though the microscopic Hamiltonians of the corresponding parent states may differ radically from each other.
