Why zero chemical potential does not allow the Bose-Einstein Condensation of Phonons?
Bose-Einstein condensation of photons and phonons
However, there are systems where the chemical potential is intrinsically zero even at high temperatures and low densities. … The former is related to the interaction with photonic modes, while the latter is related to the interaction with other particles such as phonons or defects. …
