SHEAR WAVE ATTENUATION IN SUPERCONDUCTORS,

Abstract

A general theory of the sound wave attenuation in metals is given in terms of the correlation function and is applied to the discussion of the shear wave attenuation in superconductors with the spherical Fermi surface. It is shown that the residual attenuation in the superconducting state is due to the collision drag effect. The ratio of shear wave attenuation constant in the superconducting state to that in the normal state is calculated in the two limits ql>>1 and <<1, where q is the wave number of the sound wave and l the electronic mean free path. The results confirm the theory of Claiborn and Morse (IBM Develop. 6:58 (1962)).
