The actual value of the density of states depends on the material properties (5.30) is the equation that describes the motion of non-relativistic particles under the influence of external forces. The “trajectory” in Classical Mechanics, viz. x(t) and v(t) are replaces by the wave amplitude, ψ(x,t), and the attributes we associate with ψ(x,t).
