强场中的模截断和散射
Mode truncations and scattering in strong fields
摘要：
将量子场论截断到一个主导模式提供了一种非微扰的方法来求解它们。在这里，我们考虑带电标量物质与单模电磁场的相互作用。显式洛伦兹不变性的隐含打破促使我们比较瞬时形式的量子化和前形式，后者产生显着的简化时，光前零模式。使用这些场论的结果，我们重新评估现有的第一量子化的方法在强激光场的耗尽效应的有效性，并提出了另一种解释的基础上敷料的方法QED及其红外结构。
英文摘要：
Truncating quantum field theories to a dominant mode offers a non-perturbative approach to their solution. We consider here the interaction of charged scalar matter with a single mode of the electromagnetic field. The implied breaking of explicit Lorentz invariance prompts us to compare instant-form quantisation and front-form, with the latter yielding significant simplifications when light-front zero modes are included. Using these field theory results we reassess the validity of existing first-quantised approaches to depletion effects in strong laser fields, and propose an alternative interpretation based on the dressing approach to QED and its infra-red structure.
