标题： Second-order chiral kinetic theory from Wigner function approach

摘要： 我们提出了一种系统的方法，基于量子场论逐阶从 Wigner 方程推导手征动力学理论。我们特别努力从八维手征动力学理论推导出七维手征动力学理论。我们给出了直到次经典展开第二阶的手征动力学理论。与其它方法相比，我们发现了一些新的二阶贡献。 显示英文摘要

摘要： We present a systematic method to derive the chiral kinetic theory from the Wigner equations based on quantum field theory order by order. We take special effort to derive the chiral kinetic theory in seven-dimensional phase space from the eight-dimensional chiral kinetic theory. We give the seven-dimensional chiral kinetic theory up to second order of semiclassical expansion. We find some new second-order contributions compared with other approaches.
