Power laws in a 2-leg ladder of interacting spinless fermions
L. G. Caron, C. Bourbonnais
We use the Density-Matrix Renormalization Group to study the single-particle and two-particle correlation functions of spinless fermions in the ground state of a quarter-filled lad…
On superconductivity in armchair carbon nanotubes
A. Sédéki, L. G. Caron, C. Bourbonnais
We use the momentum space renormalization group to study the influence of phonons and the Coulomb interaction on the superconducting response function of armchair single-walled nan…
Electron-phonon coupling and Peierls transition in metallic nanotubes
A. Sedeki, L. G. Caron, C. Bourbonnais
We reexamine the putative Peierls transition in a (5,5) metallic nanotube. We show that the conduction electrons at the Fermi level do not couple to the longitudinal acoustic phono…
Thermodynamic Density Matrix renormalization Group Study of the Magnetic Susceptibility of Half-integer Quantum Spin Chains
S. Moukouri, L. G. Caron
It is shown that White's density matrix renormalization group technique can be adapted to obtain thermodynamic quantities. As an illustration, the magnetic susceptibility of Heisen…
Fermi Surface of The One-dimensional Kondo Lattice Model
S. Moukouri, L. G. Caron
We show a strong indication of the existence of a large Fermi surface in the one-dimensional Kondo lattice model. The characteristic wave vector of the model is found to be $k_F=(1…
Density Matrix Renormalization Group Applied to the Ground State of the XY-Spin-Peierls System
L. G. Caron, S. Moukouri
We use the density matrix renormalization group (DMRG) to map out the ground state of a XY-spin chain coupled to dispersionless phonons of frequency . We confirm the existence…
