Evidence for exclusion of the possibility of -wave superconducting-gap symmetry in Ba-doped KFeAs
Y. Ota, K. Okazaki, Y. Kotani +12
We have investigated the superconducting(SC)-gap anisotropy for several Ba-doped KFeAs samples using laser-based angle-resolved photoemission spectroscopy. We show that the…
Superconductivity in an electron band just above the Fermi level: possible route to BCS-BEC superconductivity
Kozo Okazaki, Yoshiaki Ito, Yuichi Ota +10
Conventional superconductivity follows Bardeen-Cooper-Schrieffer(BCS) theory of electrons-pairing in momentum-space, while superfluidity is the Bose-Einstein condensation(BEC) of a…
Importance of both spin and orbital fluctuations in BaFe2(As1-xPx)2 : Evidence from superconducting gap anisotropy
T. Yoshida, S. Ideta, T. Shimojima +32
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…
Anomalous dressing of Dirac fermions in the topological surface state of Bi2Se3, Bi2Te3, and CuxBi2Se3
Takeshi Kondo, Y. Nakashima, Y. Ota +8
Quasiparticle dynamics on the topological surface state of Bi2Se3, Bi2Te3, and superconducting CuxBi2Se3 are studied by 7 eV laser-based angle resolved photoemission spectroscopy.…
