Difference between Phonon and Zero-point energy

Phonon vs. Zero-point energy

In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, like solids and some liquids. Zero-point energy (ZPE) or ground state energy is the lowest possible energy that a quantum mechanical system may have.
