Translational symmetry breaking in the electronic nematic phase of BaFe2As2
K. Koshiishi, L. Liu, K. Okazaki +13
The microscopic origin of the nematicity, namely, four-fold rotational symmetry breaking in iron-based superconductors has been controversial since its discovery. In particular, it…
Important Roles of Te 5p and Ir 5d Spin-orbit Interactions on the Multi-band Electronic Structure of Triangular Lattice Superconductor Ir1-xPtxTe2
D. Ootsuki, T. Toriyama, M. Kobayashi +15
We report an angle-resolved photoemission spectroscopy (ARPES) study on a triangular lattice superconductor IrPtTe in which the Ir-Ir or Te-Te bond formation, the…
Pseudogap formation above the superconducting dome in iron-pnictides
T. Shimojima, T. Sonobe, W. Malaeb +29
The nature of the pseudogap in high transition temperature (high-Tc) superconducting cuprates has been a major issue in condensed matter physics. It is still unclear whether the hi…
Electronic structure reconstruction by orbital symmetry breaking in IrTe2
D. Ootsuki, S. Pyon, K. Kudo +10
We report an angle-resolved photoemission spectroscopy (ARPES) study on IrTe2 which exhibits an interesting lattice distortion below 270 K and becomes triangular lattice supercondu…
Electronic reconstruction through the structural and magnetic transitions in detwinned NaFeAs
M. Yi, D. H. Lu, R. G. Moore +7
We use angle-resolved photoemission spectroscopy to study twinned and detwinned iron pnictide compound NaFeAs. Distinct signatures of electronic reconstruction are observed to occu…
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…
Enhanced superconducting gaps in the tri-layer high- cuprate BiSrCaCuO
S. Ideta, K. Takashima, M. Hashimoto +15
We have investigated the optimally doped tri-layer cuprate BiSrCaCuO (Bi2223) by angle-resolved photoemission spectroscopy, and observed energy bands and F…
Universal versus Material-Dependent Two-Gap Behaviors in the High-Tc Cuprates: Angle-Resolved Photoemission Study of La2-xSrxCuO4

We have investigated the doping and temperature dependences of the pseudogap/superconducting gap in the single-layer cuprate LaSrCuO by angle-resolved photoemission…
Temperature Dependence of the Chemical Potential in NaxCoO2: Implications for the Large Thermoelectric Power
Y. Ishida, H. Ohta, A. Fujimori +1
We have performed a temperature-dependent photoemission study of a NaxCoO2 (x~0.8) epitaxial thin film prepared by the reactive solid-phase epitaxy method. The chemical potential s…
Direct observation of the mass renormalization in SrVO by angle resolved photoemission spectroscopy

We have performed an angle-resolved photoemission study of the three-dimensional perovskite-type SrVO. Observed spectral weight distribution of the coherent part in the momentu…
Thermodynamic and transport properties of underdoped cuprates from ARPES data
T. Yoshida, X. J. Zhou, H. Yagi +11
he relationship between photoemission spectra of high- cuprates and their thermodynamic and transport properties are discussed. The doping dependence of the expecte…
Nodal metallic behavior of lightly-doped LaSrCuO
T. Yoshida, X. J. Zhou, T. Sasagawa +10
Lightly-doped LaSrCuO in the so-called "insulating" spin-glass/diagonal-stripe phase has been studied by angle-resolved photoemission spectroscopy. A quasi-particle…
