Title: Optical conductivity of the type-II Weyl semimetal ${TaIrTe}_{4}$

Abstract

TaIrTe4 is an example of a candidate Weyl type-II semimetal with a minimal possible number of Weyl nodes. Four nodes are reported to exist a single plane in k-space. The existence of a conical dispersion linked to Weyl nodes has yet to be shown experimentally. Here we use optical spectroscopy as a probe of the band structure on a low-energy scale. Studying optical conductivity allows us to probe intraband and interband transitions with zero momentum. In TaIrTe₄, we observe a narrow Drude contribution and an interband conductivity that may be consistent with a tilted linear band dispersion up to 40 meV. The interband conductivity allows us to establish the effective parameters of the conical dispersion; effective velocity v = 1.1 · 10⁴ m/s and tilt γ = 0.37. The transport data, Seebeck and Hall coefficients, are qualitatively consistent with conical features in the band structure. Quantitative disagreement may be linked to the multiband nature of TaIrTe₄.

Optical signatures of multifold fermions in the chiral topological semimetal CoSi

Journal Article Xu, Bing ; Fang, Zhenyao ; Sánchez-Martínez, Miguel-Ángel ; ... - Proceedings of the National Academy of Sciences of the United States of America

We report the optical conductivity in high-quality crystals of the chiral topological semimetal CoSi, which hosts exotic quasiparticles known as multifold fermions. We find that the optical response is separated into several distinct regions as a function of frequency, each dominated by different types of quasiparticles. The low-frequency intraband response is captured by a narrow Drude peak from a high-mobility electron pocket of double Weyl quasiparticles, and the temperature dependence of the spectral weight is consistent with its Fermi velocity. By subtracting the low-frequency sharp Drude and phonon peaks at low temperatures, we reveal two intermediate quasilinear interband contributions separatedmore »« less

Low-energy excitations in type-II Weyl semimetal $T_{d} - {MoTe}_{2}$ evidenced through optical conductivity

Journal Article Santos-Cottin, D. ; Martino, E. ; Le Mardelé, F. ; ... - Physical Review Materials

Molybdenum ditelluride, MoTe₂, is a versatile material where the topological phase can be readily tuned by manipulating the associated structural phase transition. The fine details of the band structure of MoTe₂, key to understanding its topological properties, have proven difficult to disentangle experientially due to the multiband character of the material. Through experimental optical conductivity spectra, we detect two strong low-energy interband transitions. Both are linked to excitations between spin-orbit split bands. The lowest interband transition shows a strong thermal shift, pointing to a chemical potential that dramatically decreases with temperature. Finally, with the help of ab initio calculations andmore »« less

Fermi arc electronic structure and Chern numbers in the type-II Weyl semimetal candidate ${Mo}_{x} W_{1 - x} {Te}_{2}$

Journal Article Belopolski, Ilya ; Xu, Su-Yang ; Ishida, Yukiaki ; ... - Physical Review B

It has recently been proposed that electronic band structures in crystals can give rise to a previously overlooked type of Weyl fermion, which violates Lorentz invariance and, consequently, is forbidden in particle physics. It was further predicted that Mo _x W _{1 - x} Te ₂ may realize such a type-II Weyl fermion. Here, we first show theoretically that it is crucial to access the band structure above the Fermi level ε F to show a Weyl semimetal in Mo _x W _{1 - x} Te ₂ . Then, we study Mo x W _{1 - x} Te ₂ bymore »« less

Large magnetoresistance in the type-II Weyl semimetal ${WP}_{2}$

Journal Article Wang, Aifeng ; Graf, D. ; Liu, Yu ; ... - Physical Review B

In this paper, we report a magnetotransport study on type-II Weyl semimetal WP₂ single crystals. Magnetoresistance exhibits a nonsaturating Hⁿ field dependence (14 300% at 2 K and 9 T), whereas systematic violation of Kohler's rule was observed. Quantum oscillations reveal a complex multiband electronic structure. The cyclotron effective mass close to the mass of free electron m_e was observed in quantum oscillations along the b axis, while a reduced effective mass of about 0.5 m_e was observed in α-axis quantum oscillations, suggesting Fermi surface anisotropy. The temperature dependence of the resistivity shows a large upturn that cannot be explainedmore »« less

Single pair of Weyl fermions in the half-metallic semimetal $EuC d_{2} A s_{2}$ [A Single Pair of Weyl Fermions in Half-metallic EuCd₂As₂ Semimetal]

Journal Article Wang, Lin -Lin ; Jo, Na Hyun ; Kuthanazhi, Brinda ; ... - Physical Review B

Materials with the ideal case of a single pair of Weyl points (WPs) are highly desirable for elucidating the unique properties of Weyl fermions. EuCd₂As₂ is an antiferromagnetic topological insulator or Dirac semimetal depending on the different magnetic configurations. Using first-principles band-structure calculations, we show that inducing ferromagnetism in EuCd₂As₂ can generate a single pair of WPs from splitting the single pair of antiferromagnetic Dirac points due to its half-metallic nature. Analysis with a low-energy effective Hamiltonian shows that a single pair of WPs is obtained in EuCd₂As₂ because the Dirac points are very close to the zone center andmore »« less
