Maximizing Fermi surface multiplicity optimizes superconductivity in iron pnictides
Hidetomo Usui, Kazuhiko Kuroki
We study the condition for optimizing superconductivity in the iron pnictides from the lattice structure point of view. Studying the band structure of the hypothetical lattice stru…
Possible three dimensional nodes in the superconducting gap of BaFe(AsP)
Katsuhiro Suzuki, Hidetomo Usui, Kazuhiko Kuroki
We examine theoretically the superconducting state of BaFe(AsP), an isovalent doping 122 iron pnictide superconductor. We construct a three dimensional ten orbi…
Unconventional pairing originating from disconnected Fermi surfaces in the iron-based superconductor
Kazuhiko Kuroki, Hideo Aoki
For the iron-based high superconductor LaFeAsOF, we construct a minimal model, where all of the five Fe bands turn out to be involved. We then investigate the…
Electronic Structure and Electron Correlation in LaFeAsO_{1-x}F_x and LaFePO_{1-x}F_x
Walid Malaeb, Teppei Yoshida, Takashi Kataoka +10
Photoemission spectroscopy is used to investigate the electronic structure of the newly discovered iron-based superconductors LaFeAsO_{1-x}F_x and LaFePO_{1-x}F_x. Line shapes of t…
Unconventional pairing originating from disconnected Fermi surfaces in superconducting LaFeAsOF}
Kazuhiko Kuroki, Seiichiro Onari, Ryotaro Arita +4
For a newly discovered iron-based high superconductor LaFeAsOF, we have constructed a minimal model, where inclusion of all the five Fe bands is found to be n…
