论文摘要
我们对动力学方程式（KES）的自洽系统进行了详细分析，该系统描述了在空间均匀的时间依赖性的任意极化的电场的作用下，从真空中产生的电子散齿对产生。确定了动力学理论的所有基本功能的物理意义。证明KES的总系统由两个耦合的准粒子和旋转子系统及其积分组成。提出了一种投影方法，以便在两种特殊情况下获得KE系统：线性极化的外部电场和（2+1） - 石墨烯中准粒子的维度描述。我们还考虑了内部等离子体领域的能源保护法，并描述了KE系统的另一种严格推导。
We present a detailed analysis of the self-consistent system of kinetic equations (KEs) describing electron-positron pair production from vacuum under the action of a spatially homogeneous time-dependent electric field of arbitrary polarization. The physical significance of all the basic functions of the kinetic theory is ascertained. It is demonstrated that the total system of the KEs consists of two coupled quasiparticle and spin subsystems with their integrals of motion. A projection method is proposed in order to obtain the KE system in two particular cases: linearly polarized external electric field and (2+1)-dimensional description of quasiparticles in graphene. We also address the energy conservation law taking into account the internal plasma field and describe an alternative rigorous derivation of the KE system.
