The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Although the existence of nematic order in iron-based superconductors is now a well-
established experimental fact, its origin remains controversial. Nematic order breaks the …

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 …

Iron-based superconductors are well known for their complex interplay between structure,
magnetism and superconductivity. FeSe offers a particularly fascinating example. This …

Detailed knowledge of the phase diagram and the nature of the competing magnetic and
superconducting phases is imperative for a deeper understanding of the physics of iron …

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

A theory of superconductivity in the iron-based materials requires an understanding of the
phase diagram of the normal state. In these compounds, superconductivity emerges when …

The present article reviews recent experimental investigations of spin dynamics in iron-
based superconductors and their parent compounds by means of inelastic neutron …

Superconductivity in iron selenides has experienced a rapid growth, but not without major
inconsistencies in the reported properties. For alkali-intercalated iron selenides, even the …
