Title: Electrodynamic response of the type-II Weyl semimetal ${YbMnBi}_{2}$

Abstract

Weyl fermions play a major role in quantum field theory but have been quite elusive as fundamental particles. These quasi-two-dimensional bismuth layers based materials were recently designed and provide an arena for studying the interplay between anisotropic Dirac fermions, magnetism, and structural changes, allowing the formation of Weyl fermions in condensed matter. We perform an optical investigation of YbMnBi ₂ , a representative type-II Weyl semimetal, and contrast its excitation spectrum with the optical response of the more conventional semimetal EuMnBi ₂ . This comparative study allows us to disentangle the optical fingerprints of type-II Weyl fermions, but also challenges the present theoretical understanding of their electrodynamic response.

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 .

Microscopic origins of hydrodynamic transport in the type-II Weyl semimetal ${WP}_{2}$

Journal Article Coulter, Jennifer ; Sundararaman, Ravishankar ; Narang, Prineha - Physical Review B

A microscopic understanding of hydrodynamic transport in Dirac and Weyl semimetals has remained elusive in theoretical descriptions and experimental measurements. We investigate the structure and microscopic properties of transport in WP₂, a type-II Weyl semimetal exhibiting hydrodynamic transport. Here, we characterize the nature of the microscopic properties of WP₂ as a function of temperature through ab initio calculations of the relevant scattering processes, including electron-phonon and electron-electron lifetimes, and provide equivalent calculations for copper as a point of reference. Additionally, we present an approach to calculate phonon drag, a mechanism invoked in recent experiments, through predictions of a phonon-mediated electron-electronmore »« less

Observation of Fermi arcs in the type-II Weyl semimetal candidate ${WTe}_{2}$

Journal Article Wu, Yun ; Mou, Daixiang ; Jo, Na Hyun ; ... - Physical Review B

We use ultrahigh resolution, tunable, vacuum ultraviolet laser angle-resolved photoemission spectroscopy (ARPES) to study the electronic properties of WTe₂, a material that was predicted to be a type-II Weyl semimetal. The Weyl fermion states in WTe₂ were proposed to emerge at the crossing points of electron and hole pockets, and Fermi arcs connecting electron and hole pockets would be visible in the spectral function on (001) surface. Here we report the observation of such Fermi arcs in WTe₂ confirming the theoretical predictions. This provides strong evidence for type-II Weyl semimetallic states in WTe₂. Here, we also find that trivial andmore »« less

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

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

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 40more »« 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
