A model dielectric response function for metallic nanotube ropes
J. V. Alvarez, G. G. N. Angilella
We propose a model dielectric function for ropes of single-walled nanotubes distributed in a glassy graphite host medium. We study the significance of the bosonic charge excitation…
Disordered and Ordered States in a Frustrated Anisotropic Heisenberg Hamiltonian
S. Moukouri, J. V. Alvarez
We use a recently proposed perturbative numerical renormalization group algorithm to investigate ground-state properties of a frustrated three dimensional Heisenberg model on an an…
Renormalization group method for weakly coupled quantum chains: comparison with exact diagonalization
J. V. Alvarez, S. Moukouri
We show that numerical quasi-one-dimensional renormalization group allows accurate study of weakly coupled chains with modest computational effort. We perform a systematic comparis…
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…
