论文摘要
我们研究电磁场中对手性动力学方程的费用质量校正。与手性极限不同的是，费米数密度是唯一的独立分布，数量和自旋密度彼此耦合以进行大规模的费米昂系统。在$ \ hbar $中的一阶中，我们将量子校正得出了经典的壳体条件和玻尔兹曼型传输方程。对于费米质量中的线性顺序，质量校正不会改变手性动力学方程的结构，并且表现得像其他碰撞项一样。尽管质量校正已经存在于一般电磁场的经典水平，但它只是手性磁效应研究中的一级量子校正。
We study fermion mass correction to chiral kinetic equations in electromagnetic fields. Different from the chiral limit where fermion number density is the only independent distribution, the number and spin densities are coupled to each other for massive fermion systems. To the first order in $\hbar$, we derived the quantum correction to the classical on-shell condition and the Boltzmann-type transport equations. To the linear order in the fermion mass, the mass correction does not change the structure of the chiral kinetic equations and behaves like additional collision terms. While the mass correction exists already at classical level in general electromagnetic fields, it is only a first order quantum correction in the study of chiral magnetic effect.
