- W2017251508 abstract "We study the screening properties of the three cubic crystals Si, SrTiO3, and MgO, considered as prototypes of materials with various degrees of ionic and covalent bonding. First, we carry out a numerical calculation of the density induced by a short-range time-independent perturbation, in the framework of the density functional theory. The short- and medium-range features of screening are discussed and differences from and similarities with the homogeneous electron gas are stressed. Secondly, we address the question of how local fields can be mimicked by simplified models of the microscopic static dielectric function in which the screening lengths are functions of the unperturbed ground-state local density. While short-range characteristics are fairly well reproduced, we show that the oscillatory behaviour of the induced density in direct space cannot be accounted for by such models. Thirdly, we use the spectral decomposition of the one-electron static polarization response function and propose a simple way to take into account the contribution of the high-energy conduction band states without calculating them explicitly. This method lightens the numerical burden of the polarization calculation considerably and may thus open the way to the computation of static response functions of large systems." @default.
