Photocurrent in gyrotropic Weyl semimetals [PDF]
JETP Letters, 2017 We present results of a theoretical study of photocurrents in the Weyl semimetals belonging to the gyrotropic symmetry classes. We show that, in weakly gyrotropic symmetry classes C$_{nv}$ ($n = 3,4,6$), the circular photocurrent transverse to the incidence direction appears only with account, in the electron effective Hamiltonian, for both linear and ...

Experimental Discovery of Weyl Semimetal TaAs
Physical Review X, 2015 Weyl semimetals are a class of materials that can be regarded as three-dimensional analogs of graphene upon breaking time-reversal or inversion symmetry.

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.

Surface plasmons in Weyl semimetals [PDF]
Journal of Physics: Condensed Matter, 2018 Abstract The surface plasmon excitation spectrum is calculated for the Weyl semimetal within the random phase approximation. Recently, a surface plasmon mode has been predicted to exist at the three-dimensional Dirac semimetal surface due to the Dirac plasmon mode in the bulk.

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.

Weyl semimetal/insulator transition from holography
Journal of High Energy Physics, 2018 We study a holographic model which exhibits a quantum phase transition from the strongly interacting Weyl semimetal phase to an insulating phase. In the holographic insulating phase there is a hard gap in the real part of frequency dependent diagonal ...

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 ...

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.
