Theoretical study of the magnetism in the incommensurate phase of TiOCl
D. M. Mastrogiuseppe, M. E. Torio, C. J. Gazza +1
Going beyond a recently proposed microscopic model for the incommensurate transition in the spin-Peierls TiOX (X=Cl, Br) compounds, in the present work we start by studying the the…
Incommmensurability and unconventional superconductor to insulator transition in the Hubbard model with bond-charge interaction
A. A. Aligia, A. Anfossi, L. Arrachea +6
We determine the quantum phase diagram of the one-dimensional Hubbard model with bond-charge interaction X in addition to the usual Coulomb repulsion U at half-filling. For large e…
Quantum dot with ferromagnetic leads: a density-matrix renormalization group study
C. J. Gazza, M. E. Torio, J. A. Riera
A quantum dot coupled to ferromagnetically polarized one-dimensional leads is studied numerically using the density matrix renormalization group method. Several real space properti…
Two-state behaviour of Kondo trimers
M. E. Torio, K. Hallberg, C. R. Proetto
The electronic properties and spectroscopic features of a magnetic trimer with a Kondo-like coupling to a non-magnetic metallic substrate are analyzed at zero temperature. The subs…
Quantum phase diagram of the generalized ionic Hubbard model for AB chains
M. E. Torio, A. A. Aligia, G. I. Japaridze +1
We investigate the ground-state phase diagram of the Hubbard model for the AB chain with filling 1/N, where is the number of atoms per unit cell. In the strong-coupling…
Charge and spin conductance through a side-coupled quantum dot
M. E. Torio, K. Hallberg, C. Proetto
The zero-temperature magnetic field-dependent conductance of electrons through a one-dimensional non-interacting tight-binding chain with an interacting {\it side} dot is reviewed…
