Incommensurate antiferromagnetism within a slave-boson approach to a two-dimensional Hubbard Hamiltonian
Description
We calculate the properties of spiral spin phases at the mean-field level for a single-band Hubbard Hamiltonian with variable hole density, via the Kotliar-Ruckenstein slave-boson approach adapted to a regular twist of the spin quantization axes in a two-dimensional square lattice. Antiferromagnetic and spiral phases are found to coexist in equilibrium over a finite range of hole density. (orig.)
