摘要
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.
