The connection between energy and wavelength in, for example, crystal oscillations, termed the phonon dispersion relation, is a complicated function.
-
And, because the phonon and reddened photon are generated together, they share their quantum state-that is, the phonon and the photon are entangled.

-
Laser pulses were used to put the two diamonds into a state where they were entangled with one another through a shared vibration known as a phonon.
-
That's possible because phonons have a wavelength which is similar in size to a DNA helix and this allows standing waves to form, a phenomenon known as phonon trapping.

artoparts commented on the word phonon
Mode of vibration occurring in a rigid crystal lattice, such as the atomic lattice of a solid. The study of phonons is an important part of solid state physics. See also: roton.

ruzuzu commented on the word phonon
"The concept of phonons was introduced in 1932 by Russian physicist Igor Tamm. The name phonon comes from the Greek word φωνή (phonē), which translates as sound or voice because long-wavelength phonons give rise to sound."
