Abstract
We calculate the exchange-correlation energy of the homogeneous electron gas using the adiabatic connection formula and a simple model for the susceptibility. The exact exchange energy is recovered and a formula is obtained for the correlation energy, which is in good agreement with previous results. This approach is meant to be a starting point for obtaining a charge-conserving energy functional suitable for describing inhomogeneous systems.
