Magnetism and Electronic Correlations in Quasi-One-Dimensional Compounds
M. D. Coutinho-Filho, R. R. Montenegro-Filho, E. P. Raposo +2
In this contribution on the celebration of the 80th birthday anniversary of Prof. Ricardo Ferreira, we present a brief survey on the magnetism of quasi-one-dimensional compounds. T…
Doped AB_2 Hubbard Chain: Spiral, Nagaoka and RVB States, Phase Separation and Luttinger Liquid Behavior
R. R. Montenegro-Filho, M. D. Coutinho-Filho
We present an extensive numerical study of the Hubbard model on the doped AB chain, both in the weak coupling and the infinite-U limit. Due to the special unit cell topology, t…
Quasi-One-Dimensional Quantum Ferrimagnets
R. R. Montenegro-Filho, M. D. Coutinho-Filho
We present an exact diagonalization study of the half-filled Hubbard model on bipartite quasi-one-dimensional lattices. In particular, we emphasize the dependence of the ferrimagne…
