I review recent works on the symmetry and the structure of the superconducting gap in Fe-
based superconductors (FeSCs) and on the underlying pairing mechanism in these …

The development of sensible microscopic models is essential to elucidate the normal-state
and superconducting properties of the iron-based superconductors. Because these …

Starting from a microscopic itinerant model, we derive and analyze the effective low-energy
model for collective magnetic excitations in the iron pnictides. We show that the stripe …

Technological progress in material synthesis, as well as artificial realization of condensed
matter scenarios via ultra-cold atomic gases in optical lattices or epitaxial growth of thin …

Discovery of the new materials raised researchers' hopes of solving the riddle of high-
temperature superconductivity. But the unexpectedly diverse systems turned out to possess …

Experiments on the iron–pnictide superconductors appear to show some materials where
the ground state is fully gapped, and others where low-energy excitations dominate …

We present a detailed study of the symmetry and structure of the pairing gap in Fe-based
superconductors (FeSCs). We treat FeSCs as quasi-2D, decompose the pairing interaction …

We investigate the optical conductivity with light polarized along the in-plane orthorhombic a
and b axes of Ba (Fe 1− x Co x) 2 As 2 for x= 0 and 2.5% under uniaxial pressure across …

We analyze optical conductivity of a clean two-dimensional electron system in a Fermi liquid
regime near a T= 0 Ising-nematic quantum critical point (QCP) and extrapolate the results to …

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