What is Self-Consistent RPA for Particle Numbers about?

This document presents coupled self-consistent RPA equations for even and odd particle numbers. The equations are derived using the equation of motion method. For even particle numbers, this leads to the known self-consistent RPA equations. For odd particle numbers, the single particle occupation probabilities are obtained self-consistently. This couples the even and odd particle number cases based on the same correlated vacuum. The approach is applied to the solvable Lipkin and 1D Hubbard models, giving go
