Abstract: The magnetic susceptibility at absolute-zero temperature for the one-dimensional Hubbard model is studied exactly as a function of the concentration of electrons by using Lieb and Wu's theory for this system. Our analysis essentially follows Griffiths's method for the magnetic susceptibility of the one-dimensional Heisenberg antiferromagnet, and is a generalization of Takahashi's calculation to the systems with an arbitrary concentration of electrons. The ground-state energy and the magnitude of local moments at each site are also studied. Combined with the results on the susceptibility, they should suggest how the effect of the Coulomb interaction on the properties of the system at low temperatures changes with the concentration of electrons.

Spectral properties of the Hubbard model
TL;DR: The spectral properties of the repulsive Hubbard model at T = 0 were studied in this article, where the dynamical structure factors of spin and charge degrees of freedom were discussed. And the authors obtained upper bounds of excitation spectra in some phases of the two-and three-dimensional Hubbard model.

TL;DR: In this article, the electronic structure of the one dimensional Hubbard model with a less than half filling was studied by the resonating Hartree-Fock (Res HF) method, where charged and neutral solitons (S/sup+/ and S/sup 0/) and polarons (P/sup +/) were considered as basic units of quantum fluctuations in the ground state of the model.

Absence of Mott Transition in an Exact Solution of the Short-Range, One-Band Model in One Dimension
Elliott H. Lieb,F. Y. Wu +1 more
TL;DR: In this paper, the short-range, one-band model for electron correlations in a narrow energy band is solved exactly in the one-dimensional case, and the ground-state energy, wave function, and chemical potentials are obtained, and it is found that the ground state exhibits no conductor-insulator transition as the correlation strength is increased.

Effect of Correlation on the Ferromagnetism of Transition Metals
TL;DR: In this paper, the wave function for the electrons is investigated when a set of narrow bands (valence states) has its energies within a wide band (conduction states), where the valence states are linear combinations of localized states which are attached to each lattice site.
