Re: Debye model: average phonon energy at low T

The energy of a phonon is hbar omega. The energy in a given normal mode omega is

hbar omega (nbose + 1/2)

If there are zero of these phonons present then you still have the zero point energy hbar omega. But this is not part of the energy of any of the phonons.
