Webchiral magnetic effect (CME): an electric current can be induced by the strong magnetic field when the numbers of left- and right-handed fermions are not equal [1–3]. Similarly the strong magnetic field can also lead to the chiral separation effect for the chiral charge current. These effects are associated with the chiral anomaly and can be WebJul 20, 2024 · The results reveal that the chiral WQPs feature anisotropic dynamics, which falls into two typical motion modes, i.e. directional drift (chiral magnetic effect) and periodic oscillation (chiral Zitterbewegung). We theoretically find that the mechanism behind this interesting dynamical phenomenon is the special chiral relativistic Landau level.
