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

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 …
The recently discovered Fe-pnictide and chalcogenide superconductors display low- temperature properties suggesting superconducting gap structures which appear to vary …
The spontaneous reduction of rotational symmetry in a crystalline solid driven by an electronic mechanism is referred to as electronic nematicity. This phenomenon—initially …
A fundamental and unconventional characteristic of superconductivity in iron-based materials is that it occurs in the vicinity of two other instabilities. In addition to a tendency …
