Quantum transport in Dirac and Weyl semimetals: a review
Advances in Physics: X, 2017 Topological semimetals are well known for the linear energy band dispersion in the bulk state and topologically protected surface state with arc-like Fermi surface.

Weyl semimetal and nonassociative Nambu geometry [PDF]
Physical Review B, 2016 Topological materials are characterized by an electronic band structure with nontrivial topological properties. In this paper, we introduce a basis of operators for the linear space of operators spanned by charge-neutral fermion bilinears. These band projected density operators are constructed using directly the eigenfunctions of the electronic energy ...

Enhanced Weyl semimetal signature in Co3Sn2S2 Kagome ferromagnet by chlorine doping
Communications MaterialsWeyl 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.

, 2018 Weyl semimetals, named after the physicist Hermann Weyl, were predicted theoretically about ten years ago and were found experimentally only in 2015. The topological properties of Weyl semimetals and their analogy to massless elementary particles make them a field of great interest in condensed matter physics.

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

Weyl Geometry in Weyl Semimetals
A novel oscillatory behaviour of the DC conductivity in Weyl semimetals with vacancies has recently been identified, occurring in the absence of external magnetic fields. Here, we argue that this effect has a geometric interpretation in terms of a magnetic-like field induced by an emergent Weyl connection.

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 AdvancesAlthough 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.
