Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs

Nature Communications, 2017
The study of lattice vibrations coupled to electronic excitations may provide an avenue for exploring exotic physical phenomena. Here, Xuet al. observe a Fano resonance in the Weyl semimetal TaAs, revealing evidence for a strong coupling between phonons ...

Orthorhombic TaAs: A New Topological Phase of the Archetypical Weyl Semimetal

We report on a new, topologically nontrivial phase of TaAs identified in thin TaAs layers grown by molecular beam epitaxy. Structural investigations clearly show a new atom arrangement, confirmed by the presence of 104 reflections in the X-ray ...

Boltzmann equation and semi-classical magnetoconductivity in Weyl semimetal

, 2016
Weyl semimetal is a kind of three-dimensional material which has several band touch points in the energy band structure. These band touch points are called Weyl nodes, which are associated with a quantity called chirality.

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.

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.

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.

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.

Dipolar Weyl semimetals

Physical Review B
In time-reversal symmetry-broken Weyl semimetals, Weyl points act as monopoles and antimonopoles of the Berry curvature, with a monopole-antimonopole pair producing a net zero Berry flux. The two-dimensional (2D) planes that separate a monopole-antimonopole pair of Weyl points carry quantized Berry flux.
