Abstract
A model of glass constructed entirely with phonons is introduced and solved in closed form. It yields c p (T) ∼ T at low temperatures in the glassy phase. The fit to silica glass, requiring just a single adjustable parameter, is excellent. The model includes random scattering of normal modes and quartic anharmonicity (the latter required for stability,) but no two-level states.
