How do we describe the motion of particles in a solid?

We describe the motion of particles in a solid using the concept of phonons. Phonons are quasiparticles that represent the collective motion of particles in a lattice. They are responsible for the transfer of energy through a solid, and can be thought of as sound waves propagating through the lattice.
