摘要
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 T-pc. Fluctuations not accounted for in the mean-field approximation are important-they lower T-pc by a factor approximate to 2.5.
