Prediction of a Weyl Semimetal in Hg${}_{1-x-y}$Cd${}_x$Mn${}_y$Te

Daniel Bulmash, Chao-Xing Liu, Xiao-Liang Qi

We study strained Hg${}_{1-x-y}$Cd${}_x$Mn${}_y$Te in a magnetic field using a $\mathbf{k}\cdot \mathbf{p}$ model and predict that the system is a Weyl semimetal with two nodes in an experimental…
