Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

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 …

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

A key actor in the conventional theory of superconductivity is the induced interaction
between electrons mediated by the exchange of virtual collective fluctuations (phonons in …

High-temperature superconductivity in the iron-based materials emerges from, or sometimes
coexists with, their metallic or insulating parent compound states. This is surprising, as these …

A hallmark of the phase diagrams of quantum materials is the existence of multiple
electronic ordered states, which, in many cases, are not independent competing phases, but …

Whether a quantum critical point (QCP) lies beneath the superconducting dome has been a
long-standing issue that remains unresolved in many classes of unconventional …

High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in their …

Over the past few years iron chalcogenides have been intensively studied as part of the
wider family of iron-based superconductors, with many intriguing results reported so far on …
