Abstract
We study the bulk properties of d-wave superconductors relevant to high- 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 and . We also predict strong anisotropy in the ultrasonic attenuation when a sound wave is propagated within the a-b plane.
