Superconductivity in iron compounds
TL;DR: A detailed review of the superconductivity of FePnictide and chalcogenide (FePn/Ch) superconductors can be found in this paper.
Journal ArticleDOI
What drives nematic order in iron-based superconductors?
TL;DR: In this paper, the current theoretical and experimental state of the field of nematic order in superconductors is discussed and a review of the current literature is given. But beyond this, there is little consensus on how nematic ordering arises and whether it has an effect on superconductivity.
Journal ArticleDOI
Gap symmetry and structure of Fe-based superconductors
TL;DR: In this paper, a spin fluctuation theory and the sign-changing s-wave symmetry of superconducting gap structures was proposed to account for the nonuniversality of the gap structures of FeNictide and chalcogenide superconductors.

TL;DR: The phase diagram for an FeSe monolayer grown on a SrTiO3 substrate is reported, by tuning the charge carrier concentration over a wide range through an extensive annealing procedure, and strong indications of superconductivity are observed with a transition temperature of 65±5 K.
Journal ArticleDOI
Gap symmetry and structure of Fe-based superconductors
TL;DR: In this paper, it was shown that the properties of Fe-pnictide and chalcogenide superconductors can be explained by considering spin fluctuation theory and accounting for the peculiar electronic structure of these systems coupled with the likely sign-changing s-wave symmetry.

Iron-Based Layered Superconductor La[O1-xFx]FeAs (x = 0.05−0.12) with Tc = 26 K
TL;DR: It is reported that a layered iron-based compound LaOFeAs undergoes superconducting transition under doping with F- ions at the O2- site and exhibits a trapezoid shape dependence on the F- content.

Doping a Mott insulator: Physics of high-temperature superconductivity
TL;DR: In this paper, a review of the physics of high-temperature superconductors from the point of view of the doping of a Mott insulator is presented, with the goal of putting the resonating valence bond idea on a more formal footing.

Doping a Mott Insulator: Physics of High Temperature Superconductivity
TL;DR: In this article, Anderson's idea of the resonating valence bond (RVB) was introduced to describe the spin liquid phase of the undoped Mott insulator, and the slave-boson is introduced to enforce the constraint of no double occupation.
Journal ArticleDOI
Unconventional Superconductivity with a Sign Reversal in the Order Parameter of LaFeAsO 1-x F x
TL;DR: It is argued that the newly discovered superconductivity in a nearly magnetic, Fe-based layered compound is unconventional and mediated by antiferromagnetic spin fluctuations, though different from the usual superexchange and specific to this compound.
