Despite the wealth of experimental data on the Fe-pnictide compounds of the KFe2As2 type, K=Ba, Ca, or Sr, the main theoretical work based on multiorbital tight-binding models has been restricted so far to the study of the related 1111 compounds. This can be ascribed to the more three-dimensional electronic structure found by ab initio calculations for the 122 materials, making this system less amenable to model development. In addition, the more complicated Brillouin zone BZ of the body… 
Spin fluctuations and unconventional pairing in KFe2As2
We study the relation between the spin fluctuation and superconductivity in an heavily hole doped end material KFe$_2$As$_2$. We construct a five orbital model by approximately unfolding the
Fermi-Surface Topological Phase Transition and Horizontal Order-Parameter Nodes in CaFe2As2 Under Pressure
The almost perfect agreement between PCARS results at different pressures and theoretical predictions highlights the intimate connection between the changes in the lattice structure, a topological transition in the holelike Fermi surface sheet, and the emergence on the same sheet of an order parameter with a horizontal node line.
Electronic structure in a one-Fe Brillouin zone of the iron pnictide superconductors CsFe 2 As 2 and RbFe 2 As 2
The multiband nature of iron-pnictide superconductors is one of the keys to the understanding of their intriguing behavior. The electronic and magnetic properties heavily rely on the multiband
Electronic reconstruction through the structural and magnetic transitions in detwinned NaFeAs
We use angle-resolved photoemission spectroscopy to study twinned and detwinned iron pnictide compound NaFeAs. Distinct signatures of electronic reconstruction are observed to occur at the structural
Possible Three-Dimensional Nodes in the s± Superconducting Gap of BaFe2(As1-xPx)2
We theoretically examine the superconducting state of BaFe 2 (As 1- x P x ) 2 , an isovalent doping 122-iron-pnictide superconductor. We construct a three-dimensional 10-orbital model by
Orbital and Pauli limiting effects in heavily doped Ba0.05K0.95Fe2As2
We investigated the thermodynamic properties of the Fe-based lightly disordered superconductor Ba0.05K0.95Fe2As2 in external magnetic field H applied along the FeAs layers (H ||ab planes). The
The Order-Parameter Symmetry and Fermi Surface Topology of 122 Fe-Based Superconductors: A Point-Contact Andreev-Reflection Study
We report on the results of directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe1−xCox)2As2 single crystals and epitaxial c-axis oriented films with x=0.08 as well as in
Importance of both spin and orbital fluctuations in BaFe2(As1-xPx)2 : Evidence from superconducting gap anisotropy
In the iron pnictide superconductors, two distinct unconventional mechanisms of superconductivity have been put forth: One is mediated by spin fluctuations leading to the s+- state with sign change
