Electronic Correlations within Fermionic Lattice Models

M. Matlak, B. Grabiec, S. Krawiec

We investigate two-site electronic correlations within generalized Hubbard model, which incorporates the conventional Hubbard model (parameters: $t$ (hopping between nearest neighb…

Magnetism and superconductivity within extended Hubbard model for a dimer. Exact results

B. Grabiec, S. Krawiec, M. Matlak

We find the eigenvalues $E_{α}$ and eigenvectors $∣ E_{α} >$ of the extended Hubbard dimer and we represent each part $E_{α} ∣ E_{α} >< E_{α} ∣$ of the dimer Hamiltonian $(α = 1, 2, ..., 16)$ in the…
