What is the difference between the nagaoka and Thompson model?

The Nagaoka model and the Thompson model are both theoretical frameworks used to describe the behavior of electrons in solid-state physics, particularly in the context of superconductivity. The Nagaoka model focuses on the effects of strong correlations in systems with a single hole in a half-filled band, emphasizing the role of magnetic interactions. In contrast, the Thompson model is often associated with the study of electron-phonon interactions and their impact on superconducting properties, particularly in layered materials. Overall, the key difference lies in their focus: Nagaoka emphasizes magnetic correlations, while Thompson addresses electron-phonon coupling.
