High-temperature superconductivity in iron pnictides and chalcogenides emerges when a
magnetic phase is suppressed. The multi-orbital character and the strength of correlations …

The multiband nature of iron pnictides gives rise to a rich temperature-doping phase
diagram of competing orders and a plethora of collective phenomena. At low dopings, the …

Inelastic scattering of visible light (Raman effect) offers a window into properties of
correlated metals such as spin, electron and lattice dynamics as well as their mutual …

The charge and spin dynamics of the structurally simplest iron-based superconductor, FeSe,
may hold the key to understanding the physics of high temperature superconductors in …

The detailed optical properties have been determined for the iron-based materials A Fe 2 As
2, where A= Ca, Sr, and Ba, for light polarized in the iron-arsenic (ab) planes over a wide …

The unusual temperature dependence of the resistivity and its in-plane anisotropy observed
in the Fe-based superconducting materials, particularly Ba (Fe 1-x Co x) 2 As 2, has been a …

Single crystals of the iron-pnictide compound BaFe 2 (As 1− x P x) 2 for x∼ 0.23, with a
doping concentration near quantum criticality and enhanced nematic fluctuating state in the …

An important feature of the iron-based pnictides is their multi-band electronic structure with
both electron and hole bands at the Fermi level. The size of these pockets can be changed …

We hereby present a comprehensive study of polycrystalline YbFe2As2 which includes
detailed investigation on the specific heat capacity and Raman spectroscopy measurements …

We propose an effective model to describe the A 2 g signal in Raman scattering experiments
in the URu 2 Si 2 compound. We follow the scheme proposed earlier by DV Khveshchenko …
