Ferromagnetism in the Hubbard model: Influence of the lattice structure
T. Herrmann, W. Nolting
By use of the spectral density approach the influence of the lattice structure on the possibility of ferromagnetism in the single band Hubbard model is investigated. The d=\infty h…

Magnetism in the single-band Hubbard model
T. Herrmann, W. Nolting
A self-consistent spectral density approach (SDA) is applied to the Hubbard model to investigate the possibility of spontaneous ferro- and antiferromagnetism. Starting point is a t…
