摘要：

It is shown that in heavy-fermion systems the displacement correlation function has a Rayleigh or heat conduction pole of considerable weight. The Landau-Placzek ratio is found to be four to six orders of magnitude larger than in ordinary metals. The coupling to the heat conduction pole contributes substantially to the low temperature dependence of the longitudinal attenuation of ultrasound.
