Study of a toy model and its relation to the Hubbard model with infinite range hopping

Flavio S. Nogueira, Enrique V. Anda

A toy model of strongly correlated fermions is studied using Green function and functional integration methods. The model exhibits a metal-insulator transition as the interaction i…
