Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

Since the discovery of high T c iron-based superconductors in early 2008, more than 15,000
papers have been published as a result of intensive research. This paper describes the …

The recently discovered Fe-pnictide and chalcogenide superconductors display low-
temperature properties suggesting superconducting gap structures which appear to vary …

I review recent works on the symmetry and the structure of the superconducting gap in Fe-
based superconductors (FeSCs) and on the underlying pairing mechanism in these …

The development of sensible microscopic models is essential to elucidate the normal-state
and superconducting properties of the iron-based superconductors. Because these …

We show that the competition between magnetism and superconductivity can be used to
determine the pairing state in the iron arsenides. To this end we demonstrate that the …

We consider a model of multiband superconductivity, inspired by iron pnictides, in which
three bands are connected via repulsive pair-scattering terms. Generically, three distinct …

Despite the wealth of experimental data on the Fe-pnictide compounds of the K Fe 2 As 2
type, K= Ba, Ca, or Sr, the main theoretical work based on multiorbital tight-binding models …

Among the iron-based pnictide superconductors the material KFe 2 As 2 is unusual in that its
Fermi surface does not consist of quasinested electron and hole pockets. Here we report …

We present a detailed description of two-band quasi-two-dimensional metals with s-wave
superconducting (SC) and antiferromagnetic spin-density-wave (SDW) correlations. We …
