Small-q Phonon Mediated Unconventional Superconductivity in the Iron Pnictides

We report self-consistent calculations of the gap symmetry for the iron-based high-temperature superconductors using realistic small-q phonon mediated pairing potentials and four-band energy dispersions. When both electron and hole Fermi surface pockets are present, we obtain the nodeless \(s_\pm\)...
