Enhanced Weyl semimetal signature in Co3Sn2S2 Kagome ferromagnet by chlorine doping

Communications Materials
Weyl fermions are chiral massless fermions with exotic properties. In the first established magnetic Weyl semimetal, Co3Sn2S2, a giant anomalous Hall effect has been observed, while its Fermi energy remaining 60 meV from the Weyl points.

On Anderson Localization and Chiral Anomaly in Disordered Time-Reversal Invariant Weyl Semimetals: Nonperturbative and Berry Phase Effects

Scientific Reports, 2018
Weyl semimetal, a three-dimensional electronic system with relativistic linear energy dispersion around gapless points carrying nontrivial Berry charge, is predicted to exhibit a wealth of unique response and transport properties.

Photogalvanic response in multi-Weyl semimetals

Physical Review Research
We investigate the dependence of the photogalvanic response of a twofold degenerate multi-Weyl semimetal on its topological charge, tilt, and chemical potential.

Imaging electronic states on topological semimetals using scanning tunneling microscopy

New Journal of Physics, 2016
Following the intense studies on topological insulators, significant efforts have recently been devoted to the search for gapless topological systems. These materials not only broaden the topological classification of matter but also provide a condensed ...

Magnet-free broadband unidirectional thermal emission in gradient Weyl semimetal structure [PDF]

AIP Advances
Although nonreciprocal systems based on magneto-optical materials can support unidirectional thermal emission, they require bulky devices for applying external magnetic field and are practically unfavorable.

Evidence for Weyl fermions in a canonical heavy-fermion semimetal YbPtBi

Nature Communications, 2018
Weyl fermions are evidenced in weakly correlated electron systems, but whether they survive strong electron correlations remains obscure. Here, Guo et al.

Weyl fermion excitations in the ideal Weyl semimetal CuTlSe_{2}

Physical Review Research
An ideal Weyl semimetal is characterized by a dispersion in which only Weyl cones intersect the Fermi level, with low-energy behavior being governed by Weyl fermions.

Topological spin-orbit torque in ferrimagnetic Weyl semimetal

Physical Review Research
We theoretically find a topological spin-orbit torque (SOT) in the compensated ferrimagnetic Weyl semimetal Ti_{2}MnAl. The topological SOT arises from all the occupied states, which is free from dissipation. However, it is negligible in metallic magnets
