فونون

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. In the context of optically trapped objects, the quantized vibration mode can be defined as phonons as long as the modal wavelength of the oscillation is smaller than the size of the object. A type of quasiparticle in physics, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of interacting particles. Phonons can be thought of as quantized sound waves, similar

AI overview

A phonon is a quantum unit of vibration that arises when atoms or molecules in a solid (or some liquids) oscillate together in coordinated patterns. Phonons are useful in physics because they allow scientists to describe and predict how solids conduct heat and sound, and how they respond to temperature changes, by treating vibrations as discrete, countable entities rather than continuous waves.
