The aim of the current paper is to illustrate, in a simple example, our recent, very general, rigorous results [ 1 , 2 ] on the dynamical properties of fermions and quantum-spin systems with long-range, or mean-field, interactions, in infinite volume. We consider here the strong-coupling BCS-Hubbard model studied in [ 3 , 4 ], because this example is very pedagogical and, at the same time, physically relevant for it highlights the impact of the (screened) Coulomb repulsion on (\(s\)-wave) superconductivity.

强耦合BCS-Hubbard模型的宏观动力学

本文的目的是通过一个简单的例子说明我们最近非常普遍的严格结果[ 1个 ， 2 ]关于费米子和量子自旋系统在无限体积中具有长距离或均场相互作用的动力学性质。我们在这里考虑在[]中研究的强耦合BCS-Hubbard模型 3 ， 4 ]，因为该示例具有很高的教学意义，并且与此同时在物理上也很相关，因此突出了（屏蔽的）库仑斥力对（\（s \）波）超导性的影响。
