The chiral magnetic and chiral separation effects-quantum-anomaly-induced electric current and chiral current along an external magnetic field in parity-odd quark-gluon plasma-have received intense studies in the community of heavy-ion collision physics. We show that analogous effects occur in rotating trapped Fermi gases with Weyl-Zeeman spin-orbit coupling where the rotation plays the role of an external magnetic field. These effects can induce a mass quadrupole in the atomic cloud along the rotation axis which may be tested in future experiments. Our results suggest that the spin-orbit coupled atomic gases are potential simulators of the chiral magnetic and separation effects.
手征磁效应和手征分离效应——在宇称破坏的夸克-胶子等离子体中，量子反常诱导的沿外磁场方向的电流和手征电流——在重离子碰撞物理领域受到了广泛研究。我们表明，在具有外尔-塞曼自旋轨道耦合的旋转捕获费米气体中会出现类似的效应，其中旋转起到了外磁场的作用。这些效应可以在原子云中沿旋转轴诱导出质量四极矩，这可能在未来的实验中得到验证。我们的结果表明，自旋轨道耦合原子气体是手征磁效应和分离效应的潜在模拟器。
