The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

The surprising discovery of superconductivity in layered iron-based materials, with transition
temperatures climbing as high as 55 K, has led to thousands of publications on this subject …

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 …

We present a comprehensive study of the evolution of the nematic electronic structure of
FeSe using high-resolution angle-resolved photoemission spectroscopy (ARPES), quantum …

High-temperature superconductivity often emerges in the proximity of a symmetry-breaking
ground state. For superconducting iron arsenides, in addition to the antiferromagnetic …

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 …

Abstract Superconductivity was recently observed,,,,,, in iron-arsenic-based compounds with
a superconducting transition temperature (T c) as high as 56 K, naturally raising …

We report the discovery of superconductivity at high pressure in SrFe 2 As 2 and BaFe 2 As
2. The superconducting transition temperatures are up to 27 K in SrFe 2 As 2 and 29 K in …

We review the main ingredients for an unconventional pairing state in the ferropnictides, with
particular emphasis on interband pairing due to magnetic fluctuations. Summarizing the key …

The discovery of a new family of high-TC materials, the iron arsenides (FeAs), has led to a
resurgence of interest in superconductivity. Several important traits of these materials are …
