A first-principles-based LDA correlation functional that includes a frequency-dependent exchange (kite) correction modestly outperforms the Perdew-Wang LDA functional for lattice constants and bulk moduli of 60 solids.
The integral in the second region was calculated by Perdew, where it relies on using the simplified expression of ˜Π(2Q, yQ, ζ, rs) we found in Eq
