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 ...

Optoelectronics of Single Mixed Dislocations in Van Der Waals Core‐Shell Nanowires

Small, Volume 22, Issue 44, 7 August 2026.
Ge1‐xSnxS van der Waals core‐shell nanowires can host single helical dislocations whose character is tunable from a pure screw to a majority edge dislocation via the core‐shell lattice mismatch. Cathodoluminescence shows profound effects once an edge component is introduced, notably a lowering of the spontaneous emission quantum efficiency due to the ...

Toward Tunable Magnetic Dirac Semimetals: Mn Doping of Cd3As2

Advanced Functional Materials, Volume 36, Issue 60, 27 July 2026.
Dilute magnetic doping of topological semimetals offers a pathway to tune the topological phase via time reversal symmetry breaking. This is achieved by alloying the Dirac semimetal Cd3As2 with Mn via molecular beam epitaxy. Magnetotransport measurements provide preliminary evidence of changes to the electronic structure consistent with the emergence ...

Exactly soluble model for a fractionalized Weyl semimetal

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.

Magnetic-resonance-induced non-linear current response in magnetic Weyl semimetals

AAPPS Bulletin
In this work, we propose a geometric non-linear current response induced by magnetic resonance in magnetic Weyl semimetals. This phenomenon is in analog to the quantized circular photogalvanic effect (de Juan et al., Nat. Commun.

Discovery of a new type of topological Weyl fermion semimetal state in MoxW1−xTe2

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 ...

The discovery of dynamic chiral anomaly in a Weyl semimetal NbAs

Nature Communications, 2020
Unique electronmagnetic response of Weyl semimetals have only been reported in static field regime. Here, the authors report evidence of a dynamical chiral anomaly response realized by internal collective lattice deformation with an external static ...

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 ...
