The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

This review shows the highlights of a 4-year-long research project supported by the
Japanese Government to explore new superconducting materials and relevant functional …

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

We study the effect of the lattice structure on the spin-fluctuation-mediated superconductivity
in the iron pnictides adopting the five-band models of several virtual lattice structures of …

I review theoretical ideas and implications of experiments for the gap structure and symmetry
of the Fe-based superconductors. Unlike any other class of unconventional …

We develop an understanding of the anomalous metal state of the parent compounds of
recently discovered iron-based superconductors starting from a strong-coupling viewpoint …

In the first three years since the discovery of Fe-based high T c superconductors, scanning
tunneling microscopy (STM) and spectroscopy have shed light on three important questions …

The rich materials class of iron-based superconductors turned out to exhibit a very complex
electronic structure despite the simplicity of their crystal structures. For various approaches …

The theoretical need to study the properties of the Fe-based high-T c superconductors using
reliable many-body techniques has highlighted the importance of determining what is the …

We present a detailed study of the symmetry and structure of the pairing gap in Fe-based
superconductors (FeSCs). We treat FeSCs as quasi-2D, decompose the pairing interaction …
