Antinodal kink in the band dispersion of electron-doped cuprate
C. Y. Tang, Z. F. Lin, J. X. Zhang +11
Angle-resolved photoemission spectroscopy (ARPES) measurements have established the phenomenon of kink in band dispersion of high- cuprate superconductors. However, syst…
Observation of a singular Weyl point surrounded by charged nodal walls in PtGa
J. -Z. Ma, Q. -S. Wu, M. Song +17
Constrained by the Nielsen-Ninomiya no-go theorem, in all so-far experimentally determined Weyl semimetals (WSMs) the Weyl points (WPs) always appear in pairs in the momentum space…
Evidence of topological insulator state in the semimetal LaBi
R. Lou, B. -B. Fu, Q. N. Xu +17
By employing angle-resolved photoemission spectroscopy combined with first-principles calculations, we performed a systematic investigation on the electronic structure of LaBi, whi…
New phase transition in NaTiAsO revealed by Raman scattering
D. Chen, T. T. Zhang, Z. -D. Song +8
We performed a Raman scattering study of NaTiAsO. We identified a symmetry breaking structural transition at around K, which matches a large bump in the ele…
Topological nature of FeSeTe superconductor
Zhijun Wang, P. Zhang, Gang Xu +10
We demonstrate, using first-principles calculations, that the electronic structure of FeSeTe (=0.5) is topologically non-trivial, characterized by an odd $\mathbb…
Observation of two distinct band splittings in FeSe
P. Zhang, T. Qian, P. Richard +10
We report the temperature evolution of the detailed electronic band structure in FeSe single-crystals measured by angle-resolved photoemission spectroscopy (ARPES), including the d…
Observation of well-defined quasi-particle over a wide energy range in quasi-2D system
L. -L. Jia, Z. -H. Liu, Y. -P. Cai +12
We report the observation by angle-resolved photoemission spectroscopy measurements of a highly anisotropic Dirac-cone structure in high quality SrMnBi2 crystals. We reveal a well-…
Effects of Ru Substitution on Dimensionality and Electron Correlations in Ba(Fe_{1-x}Ru_x)_2As_2
N. Xu, T. Qian, P. Richard +12
We report a systematic angle-resolved photoemission spectroscopy study on Ba(FeRu)As for a wide range of Ru concentrations (0.15 \emph{x} 0.74). W…
Strong nodeless pairing on separate electron Fermi surface sheets in (Tl, K)FeSe probed by ARPES
X. -P. Wang, T. Qian, P. Richard +6
We performed a high-resolution angle-resolved photoemission spectroscopy study of the TlKFeSe superconductor ( K). We show the existence of t…
Absence of holelike Fermi surface in superconducting K0.8Fe1.7Se2 revealed by ARPES
T. Qian, X. -P. Wang, W. -C. Jin +8
We have performed an angle-resolved photoemission spectroscopy study of the new iron-based superconductor K0.8Fe1.7Se2 (Tc ~ 30 K). Clear band dispersion is observed with the overa…
