Strongly Correlated Electrons

Abstract
We derive exact equations for a broken scale invariance of the homogeneous electron gas HEG, and show that they lead to a closed non-linear integral equation for the density- density correlation function when evaluated to leading order in the 1/N expansion. More generally, the identity leads to a sequence of more refined systems of equations, which close on a finite number of one plasmon irreducible (1PLI) correlation functions.
