  title={Electronic structure and possible pseudogap behavior in iron based superconductors},
  author={{\'E}. Z. Kuchinskii and Mikhail V. Sadovskii},
  journal={JETP Letters},
Starting from the simplified analytic model of electronic spectrum of iron-pnictogen (chalcogen) high-temperature superconductors close to the Fermi level, we discuss the influence of antiferromagneting (AFM) scattering both for stoichiometric case and the region of possible short-range order AFM fluctuations in doped compounds. Qualitative picture of the evolution of electronic spectrum and Fermi surfaces (FS) for different dopings is presented, with the aim of comparison with existing and… Expand

This study compares four prominent RMs: CiteULike, RefWorks, Mendeley, and Zotero, in terms of features offered and the accuracy of the bibliographies that they generate, and found that RefWorks generated the most accurate citations. Expand


Pseudogap in high-temperature superconductors
The paper reviews the basic experimental facts and a number of theoretical models relevant to the understanding of the pseudogap state in high-temperature superconductors. The state is observed inExpand
Doping-dependent phase diagram of LaOMAs (M=V–Cu) and electron-type superconductivity near ferromagnetic instability
By first-principles calculations, we present a doping-dependent phase diagram of the LaOM As (M = V-Cu) family. It is characterized as a antiferromagnetic semiconductor around the LaOMnAs side and asExpand
Unusual doping dependence of the electronic structure and coexistence of spin-density-wave and superconductor phases in single crystalline Sr1-xKxFe2As2.
This work reports splittings of the band structures in Sr1-xKxFe2As2 (x=0,0.1, 0.18), and proves that the SDW and superconductivity could coexist in iron pnictides. Expand
(π, π) electronic order in iron arsenide superconductors
It is reported that the electronic structure of Ba1-xKxFe2As2 is in sharp disagreement with band structure calculations, and instead reveals a reconstruction characterized by a (π, π) wavevector. Expand
Electronic structure and unusual exchange splitting in the spin-density-wave state of the BaFe2As2 parent compound of iron-based superconductors.
The first direct measurements on the electronic structure of a parent compound of the newly discovered iron-based superconductor, BaFe2As2, are reported, which provides a foundation for further studies. Expand
Unconventional superconductivity with a sign reversal in the order parameter of LaFeAsO1-xFx.
We argue that the newly discovered superconductivity in a nearly magnetic, Fe-based layered compound is unconventional and mediated by antiferromagnetic spin fluctuations, though different from theExpand

We have carried out strong-coupling calculations using the Eliashberg formalism, which provide strong evidence for the description of the planar quasiparticles in YBa 2 Cu 3 O 7 as a nearlyExpand
Is LaFeAsO1-xFx an electron-phonon superconductor?
The results indicate that electron-phonon coupling is not sufficient to explain superconductivity in the whole family of Fe-As-based superconductors, probably due to the importance of strong-correlation effects. Expand
