通过考虑通过费米表面的Berry曲率通量，可以修改动力学理论以包含三角形反常和手征磁效应。我们展示了如何从基本的量子场理论中推导出这样的动力学理论。利用新的动力学理论，我们还计算了在次前级硬稠密圈近似下与微扰理论结果相同的宇称奇关联函数。
A kinetic theory can be modified to incorporate triangle anomalies and the chiral magnetic effect by taking into account the Berry curvature flux through the Fermi surface. We show how such a kinetic theory can be derived from underlying quantum field theories. Using the new kinetic theory, we also compute the parity-odd correlation function that is found to be identical to the result in the perturbation theory in the next-to-leading order hard dense loop approximation.
