Gap Symmetry in KFe_2As_2 and cos 4θgap component in LiFeAs
S. Maiti, M. M. Korshunov, A. V. Chubukov
We revisit the issue of the gap symmetry in KFe2As2, which is an Fe-pnictide superconductor with only hole pockets. Previous theoretical studies mostly argued for a d-wave gap in K…
Evolution of symmetry and structure of the gap in Fe-based superconductors with doping and interactions
S. Maiti, M. M. Korshunov, T. A. Maier +2
We present a detailed study of the symmetry and structure of the pairing gap in Fe-based superconductors (FeSC). We treat FeSC as quasi-2D, decompose the pairing interaction in the…
Effect of nodes, ellipticity and impurities on the spin resonance in Iron-based superconductors
S. Maiti, J. Knolle, I. Eremin +1
We analyze doping dependence of the spin resonance of an s+- superconductor and its sensitivity to the ellipticity of electron pockets, to magnetic and non-magnetic impurities, and…
Effect of Fermi Surface Nesting on Resonant Spin Excitations in Ba1-xKxFe2As2
J. -P. Castellan, S. Rosenkranz, E. A. Goremychkin +13
We report inelastic neutron scattering measurements of the resonant spin excitations in Ba1-xKxFe2As2 over a broad range of electron band filling. The fall in the superconducting t…
Relation between 2Delta/Tc and nodes in Fe-based superconductors
Saurabh Maiti, Andrey V. Chubukov
We analyze the interplay between the absence or presence of the nodes in the superconducting gap along electron Fermi surfaces (FSs) in Fe-pnictides, and 2Delta/T_c along hole FSs,…
Evolution of superconductivity in Fe-based systems with doping
S. Maiti, M. M. Korshunov, T. A. Maier +2
We study the symmetry and the structure of the gap in Fe-based superconductors by decomposing the pairing interaction obtained in the RPA into s- and d-wave components and into con…
