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.

Switching magnetization with a Weyl semimetal [PDF]
Nature Nanotechnology, 2019 Energy-efficient magnetization manipulation is a prerequisite for competitive spintronic devices. The Weyl semimetal WTe2 can act as a spin current source that enables magnetization switching of an adjacent ferromagnet at low power consumption and additionally induces chiral magnetism.

Fermi Arcs and Their Topological Character in the Candidate Type-II Weyl Semimetal MoTe_{2}
Physical Review X, 2016 We report a combined experimental and theoretical study of the candidate type-II Weyl semimetal MoTe_{2}. Using laser-based angle-resolved photoemission, we resolve multiple distinct Fermi arcs on the inequivalent top and bottom (001) surfaces.

Exactly soluble model for a fractionalized Weyl semimetal [PDF]
Physical Review Research, 2019 We construct an exactly solvable lattice model of a fractional Weyl semimetal. The low-energy theory of this strongly interacting state is that of a Weyl semimetal built out of fractionally charged fermions.

AC conductivity for a holographic Weyl semimetal
Journal of High Energy Physics, 2017 We study the AC electrical conductivity at zero temperature in a holographic model for a Weyl semimetal. At small frequencies we observe a linear dependence in the frequency. The model shows a quantum phase transition between a topological semimetal (Weyl semimetal phase) with a non vanishing anomalous Hall conductivity and a trivial semimetal.

Evidence for topological type-II Weyl semimetal WTe2
Nature Communications, 2017 Exotic transport properties of type-II Weyl semimetals have been predicted but are yet to be experimentally evidenced. Here, Li et al. report evidences of an anisotropy of negative magnetoresistance and a quantum oscillation arising from the predicted ...

Discovery of a new type of topological Weyl fermion semimetal state in MoxW1−xTe2 [PDF]
Nature Communications, 2016 A Type II Weyl fermion semimetal has been predicted in MoxW1−xTe2, but it awaits experimental evidence. Here, Belopolski et al. observe a topological Fermi arc in MoxW1−xTe2, showing it originates from a Type II Weyl fermion and offering a new platform ...

Weyl fermion excitations in the ideal Weyl semimetal CuTlSe_{2}
Physical Review ResearchAn 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.
