Non-phonon vibrational modes are crucial for understanding the properties of amorphous solids, from hard solids like structural glasses to soft solids like foams and emulsions. The authors propose a unified theory to explain the acoustic properties of structural glasses, which have been measured experimentally with scattering techniques, alongside the viscoelastic properties of foams and emulsions, measured through rheological techniques.
