Explicit approximations for the charge density of inhomogeneous materials are constructed as functionals of the Kohn-Sham potential using the Lindhard response of the homogeneous electron gas, with accuracy improving on cubic helium as the level of approximation increases.
However, since the connector potential is essentially a suitable average of the KS potential, this problem arises only marginally, and only at a few points
