Robustness of topological states to lattice instability in non-symmorphic topological insulator KHgSb
D. Chen, T. T. Zhang, C. J. Yi +8
We report a polarized Raman scattering study of non-symmorphic topological insulator KHgSb with hourglass-like electronic dispersion. Supported by theoretical calculations, we show…

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…

Observation of Fermi arc spin texture in TaAs
B. Q. Lv, S. Muff, T. Qian +15
We have investigated the spin texture of surface Fermi arcs in the recently discovered Weyl semimetal TaAs using spin- and angle-resolved photoemission spectroscopy. The experiment…
