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 …

Superconductivity develops in metals upon the formation of a coherent macroscopic
quantum state of electron pairs. Iron pnictides and chalcogenides are materials that have …

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 …

We demonstrate, using first-principles calculations, that the electronic structure of FeSe 1− x
Te x (x= 0.5) is topologically nontrivial and characterized by an odd Z 2 invariant and Dirac …

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 …

The iron-based superconductors that contain FeAs layers as the fundamental building block
in the crystal structures have been rationalized in the past using ideas based on the Fermi …

High-temperature superconductivity (HTSC) remains one of the most challenging and
fascinating mysteries in condensed matter physics. Recently, superconductivity with …

Establishing the appropriate theoretical framework for unconventional superconductivity in
the iron-based materials requires correct understanding of both the electron correlation …

Almost a decade has passed since the serendipitous discovery of the iron-based high
temperature superconductors (FeSCs) in 2008. The fact that, as in the copper oxide high …

Superconductivity emerges in proximity to a nematic phase in most iron-based
superconductors. It is therefore important to understand the impact of nematicity on the …
