Quantum transport in a compensated semimetal W2As3 with nontrivial Z2 indices
Yupeng Li, Chenchao Xu, Mingsong Shen +6
We report a topological semimetal W2As3 with a space group C2/m. Based on the first-principles calculations, band crossings are partially gapped when spin-orbit coupling is include…

Magnetoresistance of semi-metals: the case of antimony
Benoît Fauqué, Xiaojun Yang, Wojciech Tabis +5
Large unsaturated magnetoresistance has been recently reported in numerous semi-metals. Many of them have a topologically non-trivial band dispersion, such as Weyl nodes or lines.…

Anomalous Nernst and Righi-Leduc effects in MnSn: Berry curvature and entropy flow
Xiaokang Li, Liangcai Xu, Linchao Ding +5
We present a study of electric, thermal and thermoelectric response in noncollinear antiferromagnet MnSn, which hosts a large Anomalous Hall Effect (AHE). Berry curvature gen…
