Abstract: The roles of the large exchange dimensionless gradient limit, s→∞, with $$s = \left| {\nabla n\left( \varvec{r} \right)} \right|/\left( {2k_{\text{f}} \left( \varvec{r} \right)n\left( \varvec{r} \right)} \right)$$s=∇nr/2kfrnr, $$k_{\text{f}} = \left( {3\pi^{2} n\left( \varvec{r} \right)} \right)^{1/3}$$kf=3π2nr1/3, and… read more here.
