Exchange-correlation energy functional constructed from orbital-dependent coupling-constant-averaged pair correlation functions

Hiroshi Yasuhara, Masahiko Higuchi, Yoshiyuki Kawazoe

An exchange-correlation energy functional $E_{\mathrm{x}c}$ and the resultant exchange-correlation potential $v_{\mathrm{x}c}(\mathbf{r})$ in density-functional theory are proposed…
