Abstract
Emergent Lorentz symmetry and chiral anomaly are well known for playing an essential role in anomalous transport phenomena of Weyl metals. In particular, the former causes a Berry-curvature-induced orbital magnetic moment to modify the group velocity of Weyl electrons, and the latter results in the chiral magnetic effect to be responsible for a ``dissipationless'' longitudinal current channel of the bulk. In this study, we verify that these two effects can be measured in Shubnikov--de Haas (SdH) quantum oscillations, where a double-peak structure of the SdH oscillation appears to cause a kink in the Landau fan diagram. We examine three different cases which cover all possible experimental situations under external electric/magnetic fields and identify the experimental condition for the existence of the double-peak structure. We claim that interplay of the orbital magnetic moment and the chiral magnetic effect in SdH quantum oscillations is an interesting feature of the Weyl metal state.
