Spectrum of the Fermi-Linearized Extended Hubbard Model on a Dimer
The extension of the Hubbard model proposed in refs. ,  includes a diagonal term designed to account for Coulomb interaction between nearest neighbour sites. In the present note we discuss the spectrum of the fermi-linearized version of such model on a dimer, assuming spin-independent hopping amplitudes.
