Numerical Calculations of the B1g Raman Spectrum of the Two-Dimensional Heisenberg Model
A. W. Sandvik, S. Capponi, D. Poilblanc +1
The B1g Raman spectrum of the two-dimensional S=1/2 Heisenberg model is discussed within Loudon-Fleury theory at both zero and finite temperature. The exact T=0 spectrum for lattic…
Universal scaling behavior of coupled chains of interacting fermions
S. Capponi, D. Poilblanc, E. Arrigoni
The single-particle hopping between two chains is investigated by exact-diagonalizations techniques supplemented by finite-size scaling analysis. In the case of two coupled strongl…
The Ferromagnetic Kondo Model for Manganites: Phase Diagram and Charge Segregation Effects
E. Dagotto, S. Yunoki, A. L. Malvezzi +5
The phase diagram of the ferromagnetic Kondo model for manganites is investigated using computational techniques. In clusters of dimensions 1 and 2, Monte Carlo simulations in the…
Insulator-Metal Transition in One Dimension Induced by Long-Range Electronic Interactions
D. Poilblanc, S. Yunoki, S. Maekawa +1
The effects of a long range electronic potential on a one dimensional commensurate Charge Density Wave (CDW) state are investigated. Using numerical techniques it is shown that a t…
Dynamical properties of the spin-Peierls compound α'--NaV2O5
D. Augier, D. Poilblanc, S. Haas +2
Dynamical properties of the novel inorganic spin-Peierls compound α'--NaV2O5 are investigated using a one-dimensional dimerized Heisenberg model. By exact diagonalizations of chain…
Integrability and coherence of hopping between 1D correlated electron systems (Reply Comment)
Frederic Mila, Didier Poilblanc
The main point of Clarke and Strong's comment, namely that our results concerning the effect of integrability on the hopping of electrons between chains are probably not related to…
