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 …

Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

High-temperature superconductivity in the iron-based materials emerges from, or sometimes
coexists with, their metallic or insulating parent compound states. This is surprising, as these …

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 …

High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in their …

We show that electron-and hole-doped BaFe 2 As 2 are strongly influenced by a Mott
insulator that would be realized for half-filled conduction bands. Experiments show that …

Starting from a microscopic itinerant model, we derive and analyze the effective low-energy
model for collective magnetic excitations in the iron pnictides. We show that the stripe …

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

Angle resolved photoemission spectroscopy (ARPES) reveals the features of the electronic
structure of quasi-two-dimensional crystals which are crucial for spin and charge ordering …

In a superconductor electrons form pairs and electric transport becomes dissipation-less at
low temperatures. Recently discovered iron-based superconductors have the highest …
