Analytical solution for two correlated particles in a Hubbard model

The extended Hubbard Hamiltonian is solved analytically for the case of two-particles in an infinite one-dimensional lattice, using a real-space map ping method and the Green function technique. The results obtained are in agreement with the numerical solution previously reported by O..Navarro and C...

Sumario:The extended Hubbard Hamiltonian is solved analytically for the case of two-particles in an infinite one-dimensional lattice, using a real-space map ping method and the Green function technique. The results obtained are in agreement with the numerical solution previously reported by O..Navarro and C. Wang Solid State Commun. 83, 473 (1992).
