The extended Hubbard model applied to study the pressure effects for High Temperature Superconductors
E. V. L. de Mello, C. Acha
We make use of a BCS type approach based on the extended Hubbard Hamiltonian to study the superconductor transition and to give a microscopic interpre- tation of the pressure effec…

Dynamical Properties of small Polarons
E. V. L. de Mello, J. Ranninger
On the basis of the two-site polaron problem, which we solve by exact diagonalization, we analyse the spectral properties of polaronic systems in view of discerning localized from…

Study of the Phase Diagram and the Tc Pressure Dependence for HgBaCuO Superconductors
E. V. L. de Mello, C. Acha
We apply a method recently derived based on the extended Hubbard Hamiltonian and the BCS approach to obtain the superconducting critical temperature dependence with carrier density…
