Topological states and topological phase transition in Cu2SnS3 and Cu2SnSe3
Liqin Zhou, Yuting Qian, Changming Yue +4
Based on the first-principles calculations within local density approximation and model analysis, we propose that the iso-structural compounds Cu2SnS3 and Cu2SnSe3 are both the sim…
Unconventional Materials: the mismatch between electronic charge centers and atomic positions
Jiacheng Gao, Yuting Qian, Huaxian Jia +5
The complete band representations (BRs) have been constructed in the work of topological quantum chemistry. Each BR is expressed by either a localized orbital at a Wyckoff site in…
Spectroscopic Evidence on Realization of a Genuine Topological Nodal Line Semimetal in LaSbTe
Yang Wang, Yuting Qian, Meng Yang +19
The nodal line semimetals have attracted much attention due to their unique topological electronic structure and exotic physical properties. A genuine nodal line semimetal is quali…

Shaosheng Yue, Yuting Qian, Meng Yang +11
Magnetic topological materials, in which the time-reversal symmetry is broken, host various exotic quantum phenomena, including the quantum anomalous Hall effect, axion insulator s…
Magnetic and electronic properties of a topological nodal line semimetal candidate: HoSbTe
Meng Yang, Yuting Qian, Dayu Yan +7
We report the experimental and theoretical studies of a magnetic topological nodal line semimetal candidate HoSbTe. Single crystals of HoSbTe are grown from Sb flux, crystallizing…
High-throughput screening for Weyl Semimetals with S Symmetry

Based on irreducible representations (or symmetry eigenvalues) and compatibility relations, a material can be predicted to be a topological/trivial insulator [satisfying compatibil…
Weyl Semimetals with symmetry
Yuting Qian, Jiacheng Gao, Zhida Song +4
In the time-reversal-breaking centrosymmetric systems, the appearance of Weyl points can be guaranteed by an odd number of all the even/odd parity occupied bands at eight inversion…
Layer Construction of Topological Crystalline Insulator LaSbTe
Yuting Qian, Zhiyun Tan, Tan Zhang +5
Topological crystalline insulator (TCI) is one of the symmetry-protected topological states. Any TCI can be deformed into a simple product state of several decoupled two-dimensiona…
Symmetry-Enforced Weyl Phonons
Qing-Bo Liu, Yuting Qian, Hua-Hua Fu +1
In spinful electronic systems, time-reversal symmetry makes that all Kramers pairs at the time-reversal-invariant momenta are Weyl points (WPs) in chiral crystals. Here, we find th…
