Many experimental findings in the materials family of cuprate superconductors are
converging towards an electronic picture which involves strong local Coulomb correlations …

We review concepts and effects of electron correlations in the copper-oxide
superconductors. The purpose of this article is twofold. First, we provide an overview of …

We study the normal state of the 2D attractive Hubbard model using quantum Monte Carlo
simulations. We show that singlet pairing correlations develop above T c, and the normal …

We have carried out strong-coupling calculations using the Eliashberg formalism for YBa 2
Cu 3 O 7. We consider the influence of potential impurity scattering on T c. We find that, as …

We review recent results for the properties of doped antiferromagnets, obtained by the
numerical analysis of the planar tJ model using the novel finite-temperature Lanczos method …

High-Temperature Superconductors provides an up-to-date and comprehensive review of
the properties of these fascinating materials. Much has been learned about the behavior and …

Neutron experiments have indicated that the structure factor S (q, ω) for the two cuprates
YBa 2 Cu 3 O 7− δ and La 2− x Sr x CuO 4 has a different q dependence. Commensurate …

After a mention of the structural, magnetic and electronic properties of high-temperature
superconductors (HTSC), the basic principles of NMR-NQR experiments in these …

We report an extensive study of magnetic excitations in fully oxygenated Y Ba 2 Cu 3 O 7,
using neutron scattering with and without spin polarization analysis. By calibrating the …

I study a model in which quasiparticles on a two-dimensional square lattice interact via
exchange of antiferromagnetic spin fluctuations, determining when one may write the …
