    • Note that our two-band model differs conceptually from the two-band model based on the dyz and dxz orbitals considered in Ref.. Band-structure calculations (Ref.) show that not only dyz and dxz orbitals but all Fe 5d orbitals contribute to the bands crossing the Fermi level, and, besides, Fe 5d orbitals strongly hybridize with the As p states. The tight-binding model of the pnictides then should include eight bands in the unfolded BZ. Our model with two hybridized orbitals and two bands crossing the Fermi level is not related to actual Fe 5d and As p orbitals, and is simply a phenomenological minimal model to describe SDW and superconductivity.

    • The behavior of 1/ T1 is further complicated by the presence of four Fermi surfaces and the variation in the gap size between the two Fermi surfaces near the same momenta, as evidenced by ARPES measurements (Ref.).
