How? What wave? Have you ever seen how we quantize the electromagnetic field to get photons? It is the same idea, photons might be real...

I was referring to the collective lattice displacement field (the deviation of atoms from equilibrium).The reason I phrased it as 'the...

Indeed, in Kittel's discussion of phonons, it states: "A phonon of wavevector ##\mathbf{k}## will interact with particles such as...

You are right it is a short hand to avoid "excitation of mode ##\omega,\mathbf k##". But in second quantization treatment, this is...

I am currently reading Kittel's Introduction to Solid State Physics and am confused by the terminology regarding phonons. On page 99...
