Anomalous Hall Effect in ZrTe5
Tian Liang, Jingjing Lin, Quinn Gibson +9
ZrTe has been of recent interest as a potential Dirac/Weyl semimetal material. Here, we report the results of experiments performed via in-situ 3D double-axis rotation to extra…
Colossal negative magnetoresistance in the complex charge density wave regime of an antiferromagnetic Dirac semimetal
Ratnadwip Singha, Kirstine J. Dalgaard, Dmitry Marchenko +10
Colossal magnetoresistance (MR) is a well-known phenomenon, notably observed in hole-doped ferromagnetic manganites. It remains a major research topic due to its potential in techn…
Anomalous Nernst Effect in Dirac Semimetal Cd3As2
Tian Liang, Jingjing Lin, Quinn Gibson +5
Dirac and Weyl semimetals display a host of novel properties. In CdAs, the Dirac nodes lead to a protection mechanism that strongly suppresses backscattering in zero magnet…
Band Engineering of Dirac Semimetals using Charge Density Waves
Shiming Lei, Samuel M. L. Teicher, Andreas Topp +13
New developments in the field of topological matter are often driven by materials discovery, including novel topological insulators, Dirac semimetals and Weyl semimetals. In the la…
High mobility in a van der Waals layered antiferromagnetic metal
Shiming Lei, Jingjing Lin, Yanyu Jia +13
Magnetic van der Waals (vdW) materials have been heavily pursued for fundamental physics as well as for device design. Despite the rapid advances, so far magnetic vdW materials are…
The Chiral Non-Centrosymmetric Superconductors TaRhB and NbRhB
Elizabeth M. Carnicom, Weiwei Xie, Tomasz Klimczuk +5
The symmetry of a material's crystal structure has a significant effect on the energy states of its electrons. Inversion symmetry, for example, results in energetically degenerate…
A pressure-induced topological phase with large Berry curvature in PbSnTe
Tian Liang, Satya Kushwaha, Jinwoong Kim +5
The picture of how a gap closes in a semiconductor has been radically transformed by topological concepts. Instead of the gap closing and immediately re-opening, topological argume…
Experimental tests of the chiral anomaly magnetoresistance in the Dirac-Weyl semimetals NaBi and GdPtBi
Sihang Liang, Jingjing Lin, Satya Kushwaha +4
In the Dirac/Weyl semimetal, the chiral anomaly appears as an "axial" current arising from charge-pumping between the lowest (chiral) Landau levels of the Weyl nodes, when an elect…
