    • Although the CF level scheme is the same for all the V sites, the octahedron axis is different from site to site, which makes a difference in CF wave functions. One should take care in defining the hopping integral between neighboring V sites. In the present paper we take the same notation as Castellani et al. A detailed description will be given in a forthcoming paper.

    • In deriving this formula, we have not included the pair hopping term for simplicity. Since this term is active only on configurations with doubly occupied orbitals, it is usually irrelevant for the low-energy physics. In fact, we confirmed by the exact diagonalization of two V clusters that the energy difference coming from the pair hopping is less than 1% for low-lying energy levels.

    • This is not the case in Castellani et al.'s picture because, although the orbital ordering corresponds to the same pattern, the electronic densities are the same at all vanadium sites.
