Ultrafast Melting of Spin Density Wave Order in BaFeAs Observed by Time- and Angle-Resolved Photoemission Spectroscopy with Extreme-Ultraviolet Higher Harmonic Generation
H. Suzuki, K. Okazaki, T. Yamamoto +13
Transient single-particle spectral function of BaFeAs, a parent compound of iron-based superconductors, has been studied by time- and angle-resolved photoemission spect…
Coherent control over three-dimensional spin polarization for the spin-orbit coupled surface state of BiSe
Kenta Kuroda, Koichiro Yaji, M. Nakayama +7
Interference of spin-up and spin-down eigenstates depicts spin rotation of electrons, which is a fundamental concept of quantum mechanics and accepts technological challenges for t…
Doping-dependent energy scale of the low-energy band renormalization in (Bi,Pb)2(Sr,La)2CuO6+d
Takeshi Kondo, Y. Nakashima, W. Malaeb +4
The nodal band-dispersion in (Bi,Pb)2(Sr,La)2CuO6+d (Bi2201) is investigated over a wide range of doping by using 7-eV laser-based angle-resolved photoemission spectroscopy. We fin…
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…
Two-Fermi-surface superconducting state and a nodal d-wave gap in the electron-doped Sm(1.85)Ce(0.15)CuO(4-d) cuprate superconductor
Andres F. Santander-Syro, Masaki Ikeda, Teppei Yoshida +6
We report on laser-excited angle-resolved photoemission spectroscopy (ARPES) in the electron-doped cuprate Sm(1.85)Ce(0.15)CuO(4-d). The data show the existence of a nodal hole-poc…
Three energy scales characterizing the competing pseudogap state, the incoherent, and the coherent superconducting state in high-Tc cuprates
Y. Okada, T. Kawaguchi, M. Ohkawa +4
We have studied the momentum dependence of the energy gap of Bi2(Sr,R)2CuOy by angleresolved photoemission spectroscopy (ARPES), particularly focusing on the difference between R=L…
