A new approach to film atoms and molecules vibrating inside solids – Phys.org

Theoretical and experimental scientists have come together to watch solids vibrate.
Atoms or molecules constitute everything around us. In many solids, like common salt or iron, they are neatly arranged as repeated structures, called ‘crystal lattices.’ The behavior of a solid to any external factor, like applied force, is determined by the collective behavior of the lattice, not individual atoms or molecules. Small vibrations of the constituents determine the collective response of the lattice….
