2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/95672We 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 ferrimagnetic ground state properties, and its associated magnetic excitations, on the Coulomb repulsion U.6 pages, 12 figures, to be published in Physica A: special issue in honor of Prof. Bernard SapovalStrongly Correlated Electronstext
