Spiral magnetism in the single-band Hubbard model: the Hartree-Fock and slave-boson approaches
TL;DR: In this paper, the ground-state magnetic phase diagram is investigated within the single-band Hubbard model for square and different cubic lattices, and the results of employing the generalized non-correlated mean-field (Hartree-Fock) approximation and generalized slave-boson approach by Kotliar and Ruckenstein with correlation effects included are compared.

TL;DR: In this article, an analysis of Dirac points is performed in terms of spinon Fermi surface in the limit of strong correlations, and application of gauge field theory to describe deconfined spin liquid phase is treated.

Spiral magnetism in the single-band Hubbard model: the Hartree–Fock and slave-boson approaches
TL;DR: The ground-state magnetic phase diagram is investigated within the single-band Hubbard model for square and different cubic lattices and it is found that the spiral states and especially ferromagnetism are generally strongly suppressed up to non-realistically large Hubbard U by the correlation effects if nesting is absent and van Hove singularities are well away from the paramagnetic phase Fermi level.

Magnetic fluctuations and itinerant ferromagnetism in two-dimensional systems with van Hove singularities
TL;DR: In this article, the authors used the quasistatic approach to analyze the criterion of ferromagnetism for two-dimensional (2D) systems with the Fermi level near Van Hove singularities (VHS) of the electronic spectrum.
