我们提出了一种新的视角来表征手性磁和相关效应的角度分解模式。我们发现向量电流和手性密度通过一个非常简单的关系联系在一起，对于所有的模态和任何质量，它以一种不受手性化学势影响的方式定义了手性磁效应的模态分解。模态分解公式对于研究旋转费米子的性质也很有用。为了证明这一点，我们给出了旋转和磁场结合产生的非零密度的直观解释，以及有限密度下手性涡效应的方法。
We present a novel perspective to characterize the chiral magnetic and related effects in terms of angular decomposed modes. We find that the vector current and the chirality density are connected through a surprisingly simple relation for all the modes and any mass, which defines the mode decomposed chiral magnetic effect in such a way free from the chiral chemical potential. The mode decomposed formulation is useful also to investigate properties of rotating fermions. For demonstration, we give an intuitive account for a nonzero density emerging from a combination of rotation and magnetic field as well as an approach to the chiral vortical effect at finite density.
