TL;DR

This paper introduces a kinetic theory approach to analyze how electronic gas interactions affect the attenuation of transversal sound waves in metals, emphasizing the role of electric fields in the long-wave limit.

Contribution

It presents a new kinetic approach considering dynamic electron-lattice interactions, differing from previous deformation-based models for sound absorption in metals.

Findings

Electric field significantly influences sound attenuation in the long-wave limit.

The kinetic model provides new insights into electron-lattice interactions affecting sound propagation.

The approach enhances understanding of sound wave damping mechanisms in metals.

Abstract

Earlier electron influence on sound absorption in metal on basis of the assumption of deformation of Fermi-surfaces under the influence of a sound wave was considered. In the present work other approach to this problem will be considered. Our approach based on the account of dynamic (kinetic) interaction of electronic gas with lattice fluctuations. The analysis of influence of electric field on process of attenuation of sound fluctuations is carried out. It is shown that in the long-wave limit this influence is essential.
