Multiple-pseudogap phases in hydrogen-doped LaFeAsO system
A. Nakamura, T. Shimojima, T. Sonobe +6
The low energy electronic structure of LaFeAsO1-xHx (0.0 < x < 0.60), the system which exhibits two superconducting domes in its phase diagram, is investigated by utilizing the las…
Point nodes persisting far beyond Tc in Bi2212
Takeshi Kondo, W. Malaeb, Y. Ishida +5
In contrast to a complex feature of antinodal state, suffering from competing order(s), the "pure" pairing gap of cuprates is obtained in the nodal region, which therefore holds th…
Observation of quasiparticles for phase incoherent d-wave pairing in Bi2212
Takeshi Kondo, W. Malaeb, Y. Ishida +3
In contrast to a complex feature of antinodal state, suffering from competing order(s), the "pure" pairing gap of cuprates is detected in the nodal region, which therefore holds th…
Evidence of a universal relation between electron-mode coupling and Tc in Ba1-xKxFe2As2 superconductor from Laser ARPES
W. Malaeb, T. Shimojima, Y. Ishida +15
We performed a Laser angle-resolved photoemission spectroscopy (ARPES) study on a wide doping range of Ba1-xKxFe2As2 (BaK) iron-based superconductor. We observed a robust low-bindi…
Electronic structure of BaNiP observed by angle-resolved photoemission spectroscopy
S. Ideta, T. Yoshida, M. Nakajima +16
We have performed an angle-resolved photoemission spectroscopy (ARPES) study of BaNiP which shows a superconducting transition at 2.5 K. We observed hole and e…
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…
