In literature:

Oscillations, again, are surgings to and fro: the crystal tends to let the "tos" go through and to stop the "fros.

Inherent oscillations and waves distort a crystal.
Phonon-Drag Thermopower at High Temperatures
So interaction of inherent oscillations with acoustic phonons is possible to track at simple univariate crystal model adding in to the equation (4) additional force -δU ′′ n .
Phonon-Drag Thermopower at High Temperatures
Obviously at the conditions ω ∗ > 0 and |q ∗ | > 0 experimental acoustic methods for crystal oscillations studies may turn out to be ineffective.
Phonon-Drag Thermopower at High Temperatures
Inherent oscillations can spread in crystals as waves of inherent oscillations.
Phonon-Drag Thermopower at High Temperatures
The phonon drag component of thermoelectric power also has confirmed the presence of inherent oscillations waves in crystals.
