MoTe2: A Type-II Weyl Topological Metal
Zhijun Wang, Dominik Gresch, Alexey A. Soluyanov +6
Based on the ab initio calculations, we show that MoTe2, in its low-temperature orthorhombic structure characterized by an X-ray diffraction study at 100 K, realizes 4 type-II Weyl…
Resonance-state-induced superconductivity at high Indium contents in In-doped SnTe
Neel Haldolaarachchige, Quinn Gibson, Weiwei Xie +3
We report a reinvestigation of superconducting SnInTe at both low and high In doping levels. Analysis of the superconductivity reveals a fundamental change as a funct…
Consequences of breaking time reversal symmetry in LaSb: a resistivity plateau and extreme magnetoresistance
F. F. Tafti, Q. D. Gibson, S. K. Kushwaha +2
Time reversal symmetry (TRS) protects the metallic surface modes of topological insulators (TIs). The transport signature of robust metallic surface modes of TIs is a plateau that…
Signature of the chiral anomaly in a Dirac semimetal: a current plume steered by a magnetic field
Jun Xiong, Satya K. Kushwaha, Tian Liang +4
In this talk, we describe recent experimental progress in detecting the chiral anomaly in the Dirac semimetal NaBi in the presence of a magnetic field. The chiral anomaly, whic…
Lifshitz transition and van Hove singularity in a Topological Dirac Semimetal
Su-Yang Xu, Chang Liu, I. Belopolski +20
A topological Dirac semimetal is a novel state of quantum matter which has recently attracted much attention as an apparent 3D version of graphene. In this paper, we report critica…
Anomalous conductivity tensor in the Dirac semimetal Na_3Bi
Jun Xiong, Satya Kushwaha, Jason Krizan +3
Na3Bi is a Dirac semimetal with protected nodes that may be sensitive to the breaking of time-reversal invariance in a magnetic field B. We report experiments which reveal that bot…
Observation of Fermi Arc Surface States in a Topological Metal: A New Type of 2D Electron Gas beyond Z2 Topological Insulators
Su-Yang Xu, Chang Liu, Satya K. Kushwaha +15
In a topological insulator, it is the electrons on the surface or edge that carry the signature of topology. Recently, a novel topological state has been proposed in metals or semi…
Bulk crystal growth and electronic characterization of the 3D Dirac Semimetal Na3Bi
Satya K. Kushwaha, Jason W. Krizan, Benjamin E. Feldman +11
High quality hexagon plate-like Na3Bi crystals with large (001) plane surfaces were grown from a molten Na flux. The freshly cleaved crystals were analyzed by low temperature scann…
