Review of experiments on the chiral anomaly in Dirac-Weyl semimetals
N. P. Ong, Sihang Liang
We provide a review of recent experimental results on the chiral anomaly in Dirac/Weyl semimetals. After a brief introduction, we trace the steps leading to the prediction of mater…
A gap-protected zero-Hall effect state in the quantum limit of the nonsymmorphic metal KHgSb
Sihang Liang, Satya Kushwaha, Tong Gao +8
A recurring theme in topological matter is the protection of unusual electronic states by symmetry, for example, protection of the surface states in Z2 topological insulators by ti…
Experimental tests of the chiral anomaly magnetoresistance in the Dirac-Weyl semimetals NaBi and GdPtBi
Sihang Liang, Jingjing Lin, Satya Kushwaha +4
In the Dirac/Weyl semimetal, the chiral anomaly appears as an "axial" current arising from charge-pumping between the lowest (chiral) Landau levels of the Weyl nodes, when an elect…
The chiral anomaly and thermopower of Weyl fermions in the half-Heusler GdPtBi
Max Hirschberger, Satya Kushwaha, Zhijun Wang +5
The Dirac and Weyl semimetals are unusual materials in which the nodes of the bulk states are protected against gap formation by crystalline symmetry. The chiral anomaly~\cite{Adle…
