Anisotropic transport in the overdoped High-Tc superconductors within the Van Hove scenario
Belen Valenzuela, Maria A. H. Vozmediano
Recent Raman experiments [F. Venturini et al., Phys. Rev. Lett. {\bf 89}, 107003-1,(2002)] done in have found that antinodal quasiparticles become insulatin…
Many body effects on - axis properties: out of plane coherence and bilayer splitting
F. Guinea, M. P. Lopez-Sancho, M. A. H. Vozmediano
The out-of-plane hopping in layered metals with strong electronic correlation is analyzed theoretically. By studying the effects of in-plane interactions on the interlayer tunnelli…
The magnetism of the t-t' Hubbard model
B. Valenzuela, M. A. H. Vozmediano, F. Guinea
The magnetic properties of the t-t' Hubbard Model in the two dimensional square lattice are studied within an unrestricted Hartree-Fock approximation in real space. The interplay b…
Phase Diagram of High-T_c Superconductors from a Field Theory Model
J. V. Alvarez, J. Gonzalez, F. Guinea +1
The renormalization group approach to correlated fermions is used to determine the phase diagram of the oxide cuprates modeled by the t-t' Hubbard model at the Van Hove filling. Sp…
