Ultrasonic attenuation in clean d-wave superconductors [PDF]

open access: yes, 1999
We consider the attenuation of longitudinal ultrasonic waves in a clean two-dimensional d-wave superconductor. We show that the attenuation coefficient is linear in temperature at low temperatures for all in-plane directions of the propagation of the ...
