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…
Emergent vortex Majorana zero mode in iron-based superconductors
Lingyuan Kong, Hong Ding
The vortex of iron-based superconductors is emerging as a promising platform for Majorana zero mode, owing to a magic integration among intrinsic vortex winding, non-trivial band t…
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…
Angle-resolved photoemission spectroscopy and its application to topological materials
Baiqing Lv, Tian Qian, Hong Ding
Angle-resolved photoemission spectroscopy (ARPES), an experimental technique based on the photoelectric effect, is arguably the most powerful method for probing the electronic stru…
Suppression of Antiferromagnetism in Electron-Doped Cuprate -
C. Y. Tang, Z. F. Lin, J. X. Zhang +11
We performed systematic angle-resolved photoemission spectroscopy measurements - on - (LCCO) thin films over the extended d…
Discovery of Ĉ rotation anomaly in topological crystalline insulator SrPb
Wenhui Fan, Simin Nie, Cuixiang Wang +12
Topological crystalline insulators (TCIs) are insulating electronic states with nontrivial topology protected by crystalline symmetries. Recently, theory has proposed new classes o…
