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

Emergent electronic phenomena in iron-based superconductors have been at the forefront
of condensed matter physics for more than a decade. Much has been learned about the …

The recent discovery of possible high-temperature superconductivity in single-layer FeSe
films, has generated significant experimental and theoretical interest,. In both the cuprate …

The record superconducting transition temperature (T c) for the iron-based high-temperature
superconductors (Fe-HTS) has long been 56 K. Recently, in single-layer FeSe films grown …

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 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 …

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 …

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

We report the superconductivity at above 30 K in a FeSe-layer compound K 0.8 Fe 2 Se 2
(nominal composition) achieved by metal K intercalating in between FeSe layers. It is …

The iron pnictide and chalcogenide compounds are a subject of intensive investigations
owing to their surprisingly high temperature superconductivity. They all share the same …
