Studying acoustic phonon for thermal conductivity, I faced a problem.  I
know that the acoutic phonon is the quantized mode of vibration occuring in
the atomic lattice of a solid.  However, I don't know how the initial atomic
vibration happen by thermal energy: the first vibration of one atom.  I
think when an atom get the thermal energy by heating, the energy well is
fluctuated, and next the nuclei starts to move.  I think this is the
mechanism of the initial atomic vibration of one atom by thermal energy.  I
wish to know whether my understanding is right or not.  Could you let me
have your answer?
Thank you very much.
