Quadratic Fermi Node in a 3D Strongly Correlated Semimetal
Takeshi Kondo, M. Nakayama, R. Chen +18
Strong spin-orbit coupling fosters exotic electronic states such as topological insulators and superconductors, but the combination of strong spin-orbit and strong electron-electro…
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…
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…
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.…
Evidence for a cos(4φ) Modulation of the Superconducting Energy Gap of Optimally Doped FeTe_{0.6}Se_{0.4} Single Crystals Using Laser Angle-Resolved Photoemission Spectroscopy
K. Okazaki, Y. Ito, Y. Ota +10
We study the superconducting(SC)-gap anisotropy of the Γ-centered hole Fermi surface in optimally doped FeTe_{0.6}Se_{0.4} (T_c = 14.5 K), using laser-excited angle-resolved photoe…
Abrupt change in the energy gap of superconducting Ba1-xKxFe2As2 single crystals with hole doping
W. Malaeb, T. Shimojima, Y. Ishida +17
We performed a Laser angle-resolved photoemission spectroscopy (ARPES) study on a wide doping range of Ba1-xKxFe2As2 (BaK) and precisely determined the doping evolution of the supe…
Common Origin of the Circular-dichroism Pattern in ARPES of SrTiO3 and CuxBi2Se3
Y. Ishida, H. Kanto, A. Kikkawa +15
Circular dichroism in the angular distribution (CDAD) of photoelectrons from SrTiO3:Nb and CuxBi2Se3 is investigated by 7-eV laser ARPES. In addition to the well-known node that oc…
