Strong-Coupling Solution of the Dynamical Mean-Field Equations for the Mott-Hubbard Insulator on a Bethe Lattice

In this work, we analyze the single-particle Green function of the Hubbard model on the Bethe lattice with an infinite number of nearest neighbors at zero temperature. The Hubbard model is conceptually the simplest many-electron model. Nevertheless, it poses a most difficult many-body problem. Exce...
