(The paper has an additional coauthor: Thomasz Sowinski; the system does not allow to add this name) Originally, the Hubbard model was derived for describing the behavior of strongly correlated electrons in solids.

The Hubbard model is the main working model in the theory of SCES. Among the real objects it best describes narrow-band transition metals and their compounds. In the case of these materials the Hubbard model is effective: it can be used to describe the magnetic and electric properties of such materials and the relationships between them. We review the slave-boson representations of the Hubbard model. When both spin and charge fermion degrees of freedom are represented by Bose fields, the approach is equivalent at the “self-consistent” saddle point level to the Gutzwiller approximation (GA).

The Fermi-Hubbard model is a key concept in condensed matter physics and provides crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature of Fermi systems poses a barrier to answering important questions concerning d-wave superconductivity and quantum magnetism. Recently, it has become possible to experimentally realize the Fermi-Hubbard model using a
