论文摘要
我们基于量子场理论开发了一种在弯曲的时空和外部电磁场中的大规模费米子的协变量理论。我们在$ O（\ hbar）$上精确地得出了四个耦合的半古典动力学方程式，它们描述了粒子数和自由度的传输。讨论了与手性动力学理论的关系。作为一种应用，我们研究了局部和全局平衡状态下有限的黎曼曲率和电磁场的存在的自旋极化。
We develop a covariant kinetic theory for massive fermions in curved spacetime and external electromagnetic field based on quantum field theory. We derive four coupled semi-classical kinetic equations accurate at $O(\hbar)$, which describe the transports of particle number and spin degrees of freedom. The relation with the chiral kinetic theory is discussed. As an application, we study the spin polarization in the presence of finite Riemann curvature and electromagnetic field in both local and global equilibrium states.
