Despite decades of intense research, the origin of high-temperature superconductivity in
cuprates and iron-based compounds is still a mystery. Magnetism and superconductivity are …

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

The parent phases of the Fe-arsenide superconductors harbor an antiferromagnetic ground
state. Significantly, the Néel transition is either preceded or accompanied by a structural …

The in-plane resistivity anisotropy is studied in strain-detwinned single crystals of FeSe. In
contrast to other iron-based superconductors, FeSe does not develop long-range magnetic …

We review the recent developments in electronic Raman scattering measurements of charge
nematic fluctuations in iron-based superconductors. A simple theoretical framework of a d …

The superconductivity discovered in iron pnictides is intimately related to a nematic ground
state, where the C 4 rotational symmetry is broken via the structural and magnetic …

Iron-based high-temperature superconductivity develops when the 'parent'antiferromagnetic/
orthorhombic phase is suppressed, typically by introduction of dopant atoms. But their …

We review our recent experimental results on the electronic nematic phase in electron-and
hole-doped BaFe 2 As 2 and FeSe. The nematic susceptibility is extracted from shear …

We show that the interference between scattering by impurities and by critical spin
fluctuations gives rise to anisotropic transport in the Ising-nematic state of the iron pnictides …

We use angle-resolved photoemission spectroscopy to study twinned and detwinned iron
pnictide compound NaFeAs. Distinct signatures of electronic reconstruction are observed to …
