Incommensurate antiferromagnetic fluctuations in the two-dimensional Hubbard model
Abstract
Commensurate and incommensurate antiferromagnetic fluctuations in the two-dimensional repulsive t-t'-Hubbard model are investigated using functional renormalization group equations. For a sufficient deviation from half filling we establish the existence of local incommensurate order below a pseudocritical temperature Tpc. Fluctuations not accounted for in the mean field approximation are important--they lower Tpc by a factor ≈2.5.
