We present a numerical solution of the parquet approximation, a conserving diagrammatic
approach which is self-consistent at both the single-particle and the two-particle levels. The …

We find that imposing crossing symmetry in the iteration process considerably extends the
range of convergence for solutions of the parquet equations for the Hubbard model. When …

The degrees of freedom that confer to strongly correlated systems their many intriguing
properties also render them fairly intractable through typical perturbative treatments. For this …

The dressed d-electron Green's function of the dp model is computed self-consistently based
on the fluctuation-exchange approximation. Using this Green's function and assuming the dx …

We study superconducting fluctuation effects on the quasi-two-dimensional dp model, which
can describe significant features of high-T c superconducting cuprates. We adopt the …

Many technologically important materials display complex behavior due to strong electronic
correlations. These include magnets, magnetoresistive materials, lanthanides and actinides …

On the basis of the two-dimensional d–p model, we analyze the correlations among the d-
electrons. We adopt the fluctuation exchange approximation in order to derive both normal …
