'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …

Angle resolved photoemission spectroscopy (ARPES) reveals the features of the electronic
structure of quasi-two-dimensional crystals which are crucial for spin and charge ordering …

The recent discovery of superconductivity with relatively high transition temperature (Tc) in
the layered iron-based quaternary oxypnictides La [O1− x F x] FeAs by Kamihara et …

A term first coined by Mott back in 1968 a “pseudogap” is the depletion of the electronic
density of states at the Fermi level, and pseudogaps have been observed in many systems …

We present results from a detailed experimental investigation of LaFeAsO, the parent
material in the series of “FeAs” based oxypnictide superconductors. Upon cooling, this …

The recent discovery of superconductivity in the iron oxypnictide family of compounds,,,,,,,,
has generated intense interest. The layered crystal structure with transition-metal ions in …

We use angle resolved photoemission spectroscopy to study the momentum dependence of
the superconducting gap in NdFeAsO 0.9 F 0.1 single crystals. We find that the Γ hole pocket …

We have performed high-resolution angle-resolved photoemission spectroscopy on heavily
overdoped KFe 2 As 2 (transition temperature T c= 3 K). We observed several renormalized …

Using the fluctuation-exchange approximation, we study an effective five-band Hubbard
model for iron-pnictide superconductors obtained from the first-principles band structure. We …

A new class of high-temperature superconductors has been discovered in layered iron
arsenic compounds. Results in this rapidly moving field may shed light on the still unsolved …
