A phonon is the collective oscillation of several atoms. Both of these concepts are very important in physics. Photon theory is the underlying theory that most of the modern physics is dependent on.
Webparticular, E = 0 is possible if x0 = xeq and p0 = 0, in other words if the object was initially at rest at the equilibrium position, then it will remain forever at rest. Before going on, let me point out that it would have been slightly easier to define u = x−xeq as the displacementoutofequilibrium, and use this as the variable.
