Abstract
Attenuation of longitudinal and transverse optical phonons in d-wave superconductors due to the electron–phonon interaction is calculated by employing the Kubo method. The electron–phonon interaction is considered in the frame of reference moving together with the lattice that allows us to exclude from consideration the inelastic electron–impurity scattering. The attenuation coefficient is calculated in the unitary limit and in the Born approximation for the electron–impurity scattering. It is found that the value and temperature dependence of the attenuation coefficient are strongly dependent on the value of the electron–impurity potential which can explain the observed sensitivity of experimental data to the sample quality.
