Adiabatic connection methods formulas

The quantity 2Ec(2)[n] is particularly important because it is the initial slope in the adiabatic connection method (coupling-constant formula) for Ec[n] [10,14-18]. In fact, quite good use of the evaluation of 2Ec(2)[n] has recently been made by Ernzerhof [19] and by Perdew, Burke, and Ernzerhof [20-23] in their modeling of...
