Fe-based superconductivity: what does ARPES tell us?

The amplitude and symmetry of the superconducting order parameter are intimately related to the pairing mechanism leading to unconventional high-temperature superconductivity in the Fe-based superconductors. Angle-resolved photoemission spectroscopy (ARPES) provides a direct characterization of the superconducting gap in the momentum space. Here I present ARPES results on ferropnictide and ferrochalcogenide superconductors suggesting that the pairing mechanism is not driven by the Fermi surface, but is rather consistent with short-range interactions. In addition, I discuss the role of the electronic correlations in these materials.
