Exactly Solvable Extended Hubbard Model

  • D. F. Wang

Abstract

In this work, we introduce long-range version of the extended Hubbard model. The system is defined on a nonuniform lattice. We show that the system is integrable. The ground state, the ground state energy, and the energy spectrum are also found for the system. Another long-range version of the extended Hubbard model is also introduced on a uniform lattice, and this system is proven to be integrable.
