Axial Magnetoelectric Effect in Dirac semimetals

Long Liang, P. O. Sukhachov, A. V. Balatsky

We propose a mechanism to generate a static magnetization via {\em axial magnetoelectric effect} (AMEE). Magnetization $\mathbf{M}\sim {\mathbf{E}}_5(\omega )\times {\mathbf{E}}_5^{\ast }(\omega )$ appears as…
