Abstract
The coupled cluster formalism is applied to ground-state correlations in jellium. A state-averaging procedure which enables us to include essentially all of the important microscopic effects at metallic densities, is shown by comparison with exact RPA results to be accurate to about 1%. Our final results at metallic densities are also compared with recent exact stochastic simulations of the many-body Schrödinger equation and seen to be accurate to the same level. They probably therefore provide the currently best available microscopic description of this systems.
