A phonon is a quasiparticle, collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids.

Phonon, in condensed-matter physics, a unit of vibrational energy that arises from oscillating atoms within a crystal. Any solid crystal, such as ordinary table salt (sodium chloride), consists …

Jun 10, 2025 · There are two main types of phonons: acoustic phonons and optical phonons. Each type affects how energy moves through a solid material in different ways. Acoustic …

A phonon is the elementary excitation in the quantum mechanical treatment of vibrations in a crystal lattice [1] or the quantum unit of a crystal lattice vibration.

1 Introduction A phonon is a collective excitation in condensed matter, which is a quantization of the vibration mode in elastic structures. Although phonons are not as popular as photons or …

Apr 7, 2024 · In the figures illustrating each phonon mode, the arrows signify the direction and “size” of the atomic displacements, which are, in fact, oscillations about the equilibrium …

Jul 8, 2010 · When one of the atoms gets pushed or pulled, it sets off a wave (or phonon) travelling through the crystal, just as sitting down on one edge of a trampoline can set off …

The evidence on the behavior of vibrational energy in periodic solids is that the collective vibrational modes can accept energy only in discrete amounts, and these quanta of energy …

A phonon is a quantum of vibrational energy that arises from the collective oscillation of atoms within a crystal lattice. In simple terms, just as a photon is a discrete packet of light energy, a …

The meaning of PHONON is a quantum of vibrational energy (as in a crystal).
