Anomalous Shubnikov-de Haas effect and observation of the Bloch-Grüneisen temperature in the Dirac semimetal ZrTe5
S. Galeski, K. Araki, O. K. Forslund +29
Appearance of quantum oscillations (QO) in both thermodynamic and transport properties of metals at low temperatures is the most striking experimental consequence of the existence…
Direct Observation of Coherent Longitudinal and Shear Acoustic Phonons in TaAs Using Ultrafast X-ray Diffraction
Min-Cheol Lee, N. Sirica, S. W. Teitelbaum +18
Using femtosecond time-resolved X-ray diffraction, we investigated optically excited coherent acoustic phonons in the Weyl semimetal TaAs. The low symmetry of the (112) surface pro…
Temperature-driven Topological Phase Transition and Intermediate Dirac Semimetal Phase in ZrTe
B. Xu, L. X. Zhao, P. Marsik +6
We present an infrared spectroscopy study of ZrTe, which confirms a recent theoretical proposal that this material exhibits a temperature-driven topological quantum phase trans…
Spatial-resolved X-ray photoelectron spectroscopy of Weyl semimetal NbAs
H. W. Liu, G. H. Zhang, P. Richard +3
We utilized X-ray photoemission electron microscopy (XPEEM) and X-ray photoelectron spectroscopy (XPS) to investigate the crystal surface of Weyl semimetal NbAs. XPEEM images prese…
Magnetotransport properties of the new-type topological semimetal ZrTe
W. L. Zhu, J. B. He, S. Zhang +4
We report the first experimental results of the magnetoresistance, Hall effect, and quantum Shubnikov-de Haas oscillations on single crystals of ZrTe, which was recently predicted…
Observation of Open-Orbit Fermi Surface Topology in Extremely Large Magnetoresistance Semimetal MoAs
R. Lou, Y. F. Xu, L. -X. Zhao +14
While recent advances in band theory and sample growth have expanded the series of extremely large magnetoresistance (XMR) semimetals in transition metal dipnictides (…
Three-component fermions with surface Fermi arcs in topological semimetal tungsten carbide
J. -Z. Ma, J. -B. He, Y. -F. Xu +19
Topological Dirac and Weyl semimetals not only host quasiparticles analogous to the elementary fermionic particles in high-energy physics, but also have nontrivial band topology ma…
Bipolar Conduction is the Origin of the Electronic Transition in Pentatellurides: Metallic vs. Semiconducting Behavior
P. Shahi, D. J. Singh, J. P. Sun +5
The pentatellurides, ZrTe5 and HfTe5 are layered compounds with one dimensional transition-metal chains that show a never understood temperature dependent transition in transport p…
Magnetotransport properties of the type II Weyl semimetal candidate Ta3S2
D. Chen, L. X. Zhao, J. B. He +8
We have investigated the magnetoresistance (MR) and Hall resistivity properties of the single crystals of tantalum sulfide, Ta3S2, which was recently predicted to be a new type II…
Experimental evidence of large-gap two-dimensional topological insulator on the surface of ZrTe5
R. Wu, J. -Z. Ma, L. -X. Zhao +12
Two-dimensional (2D) topological insulators (TIs) with a large bulk band-gap are promising for experimental studies of the quantum spin Hall effect and for spintronic device applic…
Observation of Fermi arc spin texture in TaAs
B. Q. Lv, S. Muff, T. Qian +15
We have investigated the spin texture of surface Fermi arcs in the recently discovered Weyl semimetal TaAs using spin- and angle-resolved photoemission spectroscopy. The experiment…

H. W. Liu, P. Richard, Z. D. Song +4
We report a polarized Raman study of Weyl semimetal TaAs. We observe all the optical phonons, with energies and symmetries consistent with our first-principles calculations. We det…
Observation of Weyl nodes in TaAs
B. Q. Lv, N. Xu, H. M. Weng +14
In 1929, H. Weyl proposed that the massless solution of Dirac equation represents a pair of new type particles, the so-called Weyl fermions [1]. However the existence of them in pa…
