Abstract

En 中文

A recent paper has reported that sound waves can carry gravitational mass. I analyze this effect in a Hooke's law solid, considering a wave packet moving in the z direction with an amplitude that is independent of x and y. The analysis shows that, at second order in an expansion around small-amplitude vibrations, there is a small net motion of material, and thus mass, in the direction opposite to the wave-packet propagation. This is a straightforward consequence of Newton's laws.
