On the size-consistency of the reduced-density-matrix method and the unitary invariant diagonal N-representability conditions
A promising variational approach for determining the ground state energy and its properties is by using the second-order reduced density matrix (2-RDM). However, the leading obstacle with this approach is the N-representability problem. By employing a subset of conditions (typically the P, Q, G, T1...
