FeSe, which has the simplest crystal structure among the Fe based superconductors, and
related chalcogenide superconductors are ideal candidates for investigating the detailed …

We have computed the correlated electronic structure of FeSe and its dependence on the A
1 g mode versus compression. Using the self-consistent density functional theory-dynamical …

Electronic nematicity, where strong correlations drive electrons to align in a way that lowers
the crystal symmetry, is ubiquitous among unconventional superconductors. Understanding …

Polarized Raman-scattering spectra of superconducting, single-crystalline FeSe evidence
pronounced phonon anomalies with temperature reduction. A large (∼ 6.5%) hardening of …

BaNi2As2 is a non-magnetic analogue of BaFe2As2, the parent compound of a prototype
pnictide high-temperature superconductor, displaying superconductivity already at ambient …

We present results from light scattering experiments on tetragonal FeS with the focus placed
on lattice dynamics. We identify the Raman active A 1 g and B 1 g phonon modes, a second …

Spin crossover of iron is of central importance in solid Earth geophysics. It impacts all
physical properties of minerals that altogether constitute∼ 95 vol% of the Earth's lower …

The nature of metallicity and the level of electronic correlations in the antiferromagnetically
ordered parent compounds are two important open issues for the iron-based …

Electron—phonon coupling (EPC) in cuprate and iron-based superconducting systems, as
revealed by Raman scattering, is briefly reviewed. We introduce how to extract the coupling …

We report on an investigation of the lattice dynamical properties in a range of Fe 1+ y Te 1−
x Se x compounds, with special emphasis on the c-axis polarized vibration of Fe with B 1 g …
