DMRG study of the spin gap in a one dimensional Hubbard model: effect of the distant transfer and exchange coupling
Ryotaro Arita, Kazuhiko Kuroki, Hideo Aoki +1
The spin gap of a one-dimensional repulsive Hubbard model is numerically calculated with the density matrix renormalization group, with a special emphasis on the effect of a next-n…
X-Ray Resonant Scattering as a Direct Probe of Orbital Ordering in Transition-Metal Oxides
Michele Fabrizio, Massimo Altarelli, Maurizio Benfatto
X-ray resonant scattering at the K-edge of transition metal oxides is shown to measure the orbital order parameter, supposed to accompany magnetic ordering in some cases. Virtual t…
A single chain analysis of doped quasi one dimensional spin 1 compounds: paramagnetic versus spin 1/2 doping
M. Fabrizio, R. Mélin
We present a numerical study of single chain models of doped spin 1 compounds. We use low energy effective one-dimensional models for both the cases of paramagnetic and spin-1/2 do…
Impurity in a Luttinger liquid away from half-filling: a numerical study
Shaojin Qin, Michele Fabrizio, Lu Yu +2
Conformal field theory gives quite detailed predictions for the low energy spectrum and scaling exponents of a massless Luttinger liquid at generic filling in the presence of an im…
Comment on ``Enhancement of the Tunneling Density of States in Tomonaga-Luttinger Liquids''
Michele Fabrizio, Alexander O. Gogolin
In a recent Physical Review Letter, Oreg and Finkel'stein (OF) have calculated the electron density of states (DOS) for tunneling into a repulsive Luttinger liquid close to the loc…
Non magnetic molecular Jahn-Teller Mott insulators
Michele Fabrizio, Erio Tosatti
Narrow-band conductors may turn insulating and magnetic as a consequence of strong electron-electron correlation. In molecular conductors, the concomitance of a strong Jahn-Teller…
