...4) leads to the well-known Ehrenreich and Cohen (1959) expression for the imaginary part of the macroscopic dielectric function in terms of the matrix elements of the velocity operator v between valence and conduction states:(6)...

...Later, the time-dependent Hartree approach was shown by Ehrenreich and Cohen (1959) to be equivalent to the diagrammatic bubble expansion for the dielectric function in many-body perturbation theory (see also Pines, 1963, and Pines and Nozières, 1989)....

...The frequency-dependent scattering also shows that the classical Drude model [218,443] cannot be used for detailed quantitative work unless a frequency-dependent mean scattering time or mean free path is invoked....
