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…
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 (…
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…
Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs
B. Xu, Y. M. Dai, L. X. Zhao +12
Strong coupling between discrete phonon and continuous electron-hole pair excitations can give rise to a pronounced asymmetry in the phonon line shape, known as the Fano resonance.…
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…
Nodeless superconductivity in noncentrosymmetric PbTaSe single crystals
G. M. Pang, M. Smidman, L. X. Zhao +7
We report an investigation of the superconducting order parameter of the noncentrosymmetric compound PbTaSe, which is believed to have a topologically nontrivial band structure…
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…
Raman study of lattice dynamics in Weyl semimetal TaAs
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…
