The essential challenge in orbital-free density functional theory (OF-DFT) is to construct accurate kinetic energy density functionals (KEDFs) with general applicability (i.e., transferability). During the last decade, several linear-response (LR)-based KEDFs have been proposed. Among them, the Wang-Govind-Carter (WGC) KEDF, containing a density-dependent… (More)

We derive an analytic form of the Wang-Govind-Carter ͑WGC͒ ͓Wang et al., Phys. Rev. B 60, 16350 ͑1999͔͒ kinetic energy density functional ͑KEDF͒ with the density-dependent response kernel. A real-space aperiodic implementation of the WGC KEDF is then described and used in linear scaling orbital-free density functional theory ͑OF-DFT͒ calculations.
