Realization of low-energy Dirac fermions in (IrPt)Te superconductors
Binbin Fu, Changjiang Yi, Zhijun Wang +10
Superconducting and topological states are two distinct quantum states of matter. Superconductors with topologically nontrivial electronic states provide a platform to study the in…
Observation of bulk nodal lines in topological semimetal ZrSiS
Binbin Fu, Changjiang Yi, Tiantian Zhang +13
ZrSiS is the most intensively studied topological nodal-line semimetal candidate, which is proposed to host multiple nodal lines in its bulk electronic structure. However, previous…
Observation of topological states residing at step edges of WTe2
Lang Peng, Yuan Yuan, Gang Li +5
Topological states emerge at the boundary of solids as a consequence of the nontrivial topology of the bulk. Recently, theory predicts a topological edge state on single layer tran…
Interplay of Dirac electrons and magnetism in AMnBi2 (A=Ca, Sr)
Anmin Zhang, Changle Liu, Changjiang Yi +8
Dirac materials exhibit intriguing low-energy carrier dynamics that offer a fertile ground for novel physics discovery. Of particular interest is the interplay of Dirac carriers wi…
Raman scattering study of large magnetoresistance semimetals TaAs and NbAs
Feng Jin, Xiaoli Ma, Pengjie Guo +12
We have performed polarized and temperature-dependent Raman scattering measurements on extremely large magnetoresitance compounds TaAs and NbAs. In both crystals, all the R…
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…
