Settling for One Model

The video discusses the standard model used to describe glassy materials, focusing on its application to ordinary window glass at low temperatures. It highlights the puzzling behavior of these materials and the theory that explains their disordered nature through quantum tunneling. Despite the model's limitations and lack of alternatives, it remains widely used due to its ability to fit experimental data.

What does the theory suggest about the movement of atoms in disordered materials?

Why has there been little development of alternative models for glassy materials over the past 40 years?
