SUMMARY
The formula for the speed of sound, represented as c² = (n/m) ∂²U/∂n², is derived from the relationship between vacuum energy density (U), quasiparticle number density (n), and the bare mass of the quasiparticle (m). This derivation is discussed in detail in the document available at the provided link, which presents a slightly different formulation that is equivalent to the discussed formula. Understanding this derivation is crucial for those studying the physics of sound in various mediums.
