This phrase is used in the context of solid-state physics to describe a mode of vibration in a crystal lattice where the vibrations are coherent and exhibit wave-like behavior.

Examples:

The material exhibits a coherent phonon mode at low temperatures.
The researchers studied the behavior of a coherent phonon mode in the crystal structure.
The presence of a coherent phonon mode indicates the stability of the crystal lattice.
Excitation of a coherent phonon mode can lead to interesting quantum effects.
The coherent phonon mode plays a crucial role in determining the material's properties.

N/A

Alternatives:

a coherent phonon mode
a coherent vibrational mode
a coherent lattice vibration mode
a coherent mode of lattice oscillation
a coherent mode of crystal vibration

The correct phrase is 'a coherent phonon mode.' Phonons are quantized lattice vibrations in a solid, while photons are quantized particles of light. Therefore, in the context of discussing modes related to lattice vibrations, 'phonon' is the appropriate term.
