    • This term corresponds to the Van Vleck paramagnetism in insulating materials, and becomes large when the “quenching” of the orbital angular moment is not sufficient. Moreover, this term can be enhanced by the electron correlation, since electron correlations change the electron configuration as well as the crystal field, and the Van Vleck term cannot be treated by a one-body approximation. The x-dependence of the fourth term in the (Formula presented) system is still an open question: see, e.g., H. Kontani and K. Yamada, J. Phys. Soc. Jpn. 65, 172 (1996).

    • Even in the case where only the on-site Coulomb interaction is included in the model Hamiltonian, the self-energy can be nonlocal (momentum dependent). For example, the effect of antiferromagnetic fluctuation due to Fermi surface nesting has already been discussed in the literature: A. Kampf and J. R. Schrieffer, Phys. Rev. B 41, 6399 (1990).
