Query: Two-Impurity Anderson-Kondo Model: first order Impurity-correlation   We analyze the consequences of a first-order (in the effective Kondo
coupling) inter-impurity correlation present in the Two-Impurity Anderson
Hamiltonian. This correlation generates a pair of Kondo Doublet states which
are responsible for the first (higher energy) Kondo stage of these systems.
Applied to systems of quantum dots in a semiconductor heterolayer, these
Doublets predict a mainly ferromagnetic dot-dot spin correlation which is
different than the expected from the second-order RKKY interaction. In order to
effectively screen both dots, a parallel alignment of the dot-spins is favored
by the interaction.
