A new scheme for constructing approximate effective electron potentials within density-functional theory is proposed. The scheme consists of calculating the effective potential for a series of reference systems, and then using these potentials to construct the potential of a general system. To make contact with the reference system the neutral-sphere radius of each atom is used. The scheme can simplify calculations with partial wave methods in the atomic-sphere or muffin-tin approximation…

Incomplete melting of the Si(100) surface from molecular-dynamics simulations using the effective-medium tight-binding model
Abstract We present molecular dynamics simulations of the Si(100) surface in the temperature range 1100–1750 K. To describe the total energy and forces we use the effective-medium tight-binding

TLDR
The method is applicable whenever the electron density of the coupled fragments does not deviate too markedly from a sum of isolated fragment densities and is particularly appropriate when full density-functional calculations are tractable for the isolated fragments but difficult for the coupled system.

Ab initio potential for solids.
TLDR
A total-energy theory for a solid is presented, based on density-functional theory and consists of a succession of approximations that are equivalent to the usual effective-medium theory.

TLDR
It is shown how simple tight-binding models can be understood as stationary approximations to self-consistent density-functional theory and prescriptions for calculating all the required potentials and matrix elements are given.
Comment on the average potential of a Wigner solid
Ihm and Cohen have stated that it is not true that the zero of potential in a Wigner solid is arbitrary. We argue that it is arbitrary by demonstrating that the value obtained depends on how one
