摘要：

We calculate self-consistently the momentum and energy dependence of the quasiparticle self-energy and the dynamic spin susceptibility chi(s) for the two-dimensional Hubbard model. Near the magnetic instability we find incommensurate peaks in Imchi(s)(q,omega) similar to those observed by neutron scattering in La2-xSrxCuO4. The magnetic instability itself is strongly renormalized by the self-energy corrections. The density of states exhibits a pseudogap, and the resistivity is nearly linear in T. However, we do not find spin-fluctuation-induced superconductivity.
