论文摘要
我们讨论了量子电动力学和标量量子电动动力学中的海森堡 - 束空间形式，相对于横向场。关于此类场类型的特殊特征，我们得出了修改的传输方程，因此垂直于波浪的传播方向的颗粒矩仅显示为外部参数。在空间振荡场的情况下，我们进一步演示了如何将无限顺序的动量导数操作员转变为简单的耦合项。
We discuss the Heisenberg-Wigner phase-space formalism in quantum electrodynamics as well as scalar quantum electrodynamics with respect to transverse fields. In regard to the special characteristics of such field types we derive modified transport equations such that particle momenta perpendicular to the propagation direction of the waves show up as external parameters only. In case of spatially oscillating fields we further demonstrate how to transform momentum derivative operators of infinite order into simple coupling terms.
