WebApr 21, 2016 · We observe that the ratios between the variance and the average phonon number reduce from 1 to 0.43, 0.39 and 0.2, after 1–3 single-phonon additions, respectively. WebApr 7, 2024 · One kind of excitation is called the acoustic phonon. This kind of phonon has a dispersion relation like ω = c k for small k and where c is the speed of sound. The optical phonon, however has a different dispersion relation, where ω → (non-zero constant) as k → 0. In an optical phonon, neighbouring atoms move in opposite directions.
