Microscopic theory of force constants in the adiabatic approximation
TL;DR: In this article, the Born-von Karman force constants in an arbitrary solid, crystalline or amorphous, are derived in terms of the complete inverse dielectric function of the electrons.
Microscopic theory of force constants in solids
TL;DR: In this paper, the authors derived the force constants from the energy of a neutral system of interacting nuclei and electrons, and verified that they fulfill the general symmetry, translational and rotational invariance properties required by the Born-Van Karman theory.
