On Weyl Nodes in Ferromagnetic Weyl Semimetal
Acta Physica Polonica A, 2023 The ferromagnetic Weyl semimetals, such as Co3Sn2S2, feature pairs of Weyl points characterized by the opposite chiralities.We model this type of semimetals by the inversion symmetry protected and the time reversal symmetry broken Bloch Hamiltonian. It involves terms representing the tunnelling effect, exchange field corresponding to the ferromagnetic ...

, 2022 In this work, we theoretically investigate the superluminal and subluminal reflected group delay from an air-Weyl semimetal film-Weyl semimetal substrate layered structure by using 4*4 magneto-optical matrix. We show a tunable transition between positive

All‐Electric Spin Device Operation Using the Weyl Semimetal, WTe2, at Room Temperature
Advanced Electronic Materials, 2023 Topological quantum materials (TQMs) possess abundant and attractive spin physics, and a Weyl semimetal is the representative material because of the generation of spin polarization that is available for spin devices due to its Weyl nature.

Nonlinear magnetoconductivity in Weyl and multi-Weyl semimetal in quantizing magnetic field
, 2022 Magnetotransport and magneto-optics experiments offer a very powerful probe for studying the physical properties of materials. Here, we investigate the second-order nonlinear magnetoconductivity of tilted type-I Weyl and multi-Weyl semimetal. In contrast

Emission of Photons by Quasiparticles in Weyl Semimetals [PDF]
Symmetry, 2020 We show that quasiparticles in Weyl semimetals may decay with emission of a single photon. We study the spectrum of emitted photons and estimate the decay rates.

A Raman probe of phonons and electron–phonon interactions in the Weyl semimetal NbIrTe4
Scientific Reports, 2021 There is tremendous interest in measuring the strong electron–phonon interactions seen in topological Weyl semimetals. The semimetal NbIrTe4 has been proposed to be a Type-II Weyl semimetal with 8 pairs of opposite Chirality Weyl nodes which are very ...

Disorder-driven non-Anderson transition in a Weyl semimetal. [PDF]
Proc Natl Acad Sci U S AFor several decades, it was widely believed that a non-interacting disordered electronic system could only undergo an Anderson metal-insulator transition due to Anderson localization.

Disordered Weyl Semimetals and Their Topological Family [PDF]
Physical Review Letters, 2015 We develop a topological theory for disordered Weyl semimetals in the framework of gauge invariance of replica formalism and boundary-bulk correspondence of Chern insulators. An anisotropic topological $θ$-term is analytically derived for the effective non-linear sigma model.

Linear magnetoconductivity in an intrinsic topological Weyl semimetal
New Journal of Physics, 2016 Searching for the signature of the violation of chiral charge conservation in solids has inspired a growing passion for the magneto-transport in topological semimetals.
