Abstract
We study the bulk properties of d-wave superconductors relevant to high-Tc copper oxides within weak-coupling theory. The superfluid density, the tunneling conductance, and the frequency-dependent electric conductivity appear to be quite consistent with some of the experimental data from single crystals of YBa2Cu3O7 and Bi2Sr2CaCuO8. We also predict strong anisotropy in the ultrasonic attenuation when a sound wave is propagated within the a-b plane.
