Unusual magneto-transport from Si-square nets in topological semimetal HfSiS
Nitesh Kumar, Kaustuv Manna, Yanpeng Qi +5
The class of topological semimetals comprises a large pool of compounds. Together they provide a wide platform to realize exotic quasiparticles for example Dirac, nodal line Dirac…
Topological Materials: Weyl Semimetals
Binghai Yan, Claudia Felser
Topological insulators and topological semimetals are both new classes of quantum materials, which are characterized by surface states induced by the topology of the bulk band stru…
Topological quantum phase transition and superconductivity induced by pressure in the bismuth tellurohalide BiTeI
Yanpeng Qi, Wujun Shi, Pavel G. Naumov +8
A pressure-induced topological quantum phase transition has been theoretically predicted for the semiconductor BiTeI with giant Rashba spin splitting. In this work, the evolution o…
Chiral magnetoresistance in the Weyl semimetal NbP
Anna Corinna Niemann, Johannes Gooth, Shu-Chun Wu +10
NbP is a recently realized Weyl semimetal (WSM), hosting Weyl points through which conduction and valence bands cross linearly in the bulk and exotic Fermi arcs appear. However, th…
Strong, anisotropic anomalous Hall effect and spin Hall effect in chiral antiferromagnetic compounds Mn ( = Ge, Sn, Ga, Ir, Rh and Pt)
Yang Zhang, Yan Sun, Hao Yang +4
We have carried out a comprehensive study of the intrinsic anomalous Hall effect and spin Hall effect of several chiral antiferromagnetic compounds, Mn ( = Ge, Sn, Ga, Ir,…
Topological Weyl semimetals in the chiral antiferromagnetic materials Mn3Ge and Mn3Sn
Hao Yang, Yan Sun, Yang Zhang +3
Recent experiments revealed that Mn3Sn and Mn3Ge exhibit a strong anomalous Hall effect at room temperature, provoking us to explore their electronic structures for topological pro…
