The spin-½ antiferromagnetic Heisenberg model on a square lattice is used to describe the
dynamics of the spin degrees of freedom of undoped copper oxides. Even though the model …

The properties of the Y1− xPrxBa2Cu3O7 (YPrBCO) system are reviewed. These include
superconducting, normal state, structural, chemical, optical, magnetic, and thermal …

We present an experimental review of the nature of the pseudogap in the cuprate
superconductors. Evidence from various experimental techniques points to a common …

We show that the retarded interaction between quasiparticiles on a 2D square lattice
induced by the exchange of antiferromagnetic paramagnons leads uniquely to a transition to …

The Van Hove singularity (VHS) provides a paradigm for the study of the role of peaks in the
density of states (dos) on electronic properties. More importantly, it appears to play a major …

We show that the retarded interaction between quasiparticles on a two dimensional square
lattice induced by the exchange of antiferromagnetic paramagnons leads uniquely to a …

We calculate the resistivity ρ as a function of temperature T for two models currently
discussed in connection with high-temperature superconductivity: nearly antiferromagnetic …

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 establish the applicability to transport phenomena in the cuprate superconductors of a
nearly antiferromagnetic Fermi liquid (NAFL) description of the magnetic interaction between …

We report microwave surface resistance (R s) measurements on two very-high-quality YBa 2
Cu 3 O 6.95 crystals which exhibit extremely low residual loss at 1.2 K (2-6 μΩ at 2 GHz), a …
