Rushton, P. P. and Tozer, D. J. and Clark, S. J. (2002) 'Description of exchange and correlation in the strongly inhomogeneous electron gas using a nonlocal density functional.', Physical review B., 65 (19). p. 193106.
We present exchange-correlation energy densities exc , total energies Exc, and holes, calculated for strongly inhomogeneous electron gases using the nonlocal weighted density approximation. The results closely resemble variational Monte Carlo simulations performed recently @Phys. Rev. Lett. 87, 036401 ~2001!#, demonstrating the effectiveness of a nonlocal density functional description.
