    • A variety of lattice effects in real materials keep the modulation of VDW more strongly pinned to M than in the standard FFLO case (Ref.). Thus, it is useful to identify the FFLO state with the metallic VDW (Fig. 1). Alternatively, one could draw on the current language of cold atomic gases and reserve the label FFLO for the incommensurate metallic VDW while the commensurate metallic VDW in this nomenclature becomes a "breached pairing" fictitious superconductor.

    • The introduction of the extra isospin flavor defines a minimal model within which all the interaction vertices are allowed to assume their local form. For example, the short-range on-site intraband (intraflavor) repulsion Uh (e) does not enter within our elementary SU(2) model alone since ni2 = ni for fermion particle number operators. Of course, this is not a problem at all and one simply has to look at the nonlocal intraband repulsion and pairing terms for spinless fermions but this is not what will ultimately correspond to actual pnictides, where there are two extra pairs of flavors, additional orbital and the real spin, for the total of four, and the local interactions among these flavors is all that is needed.
