相对论Laser加速中的辐射反应效应
Effects of Radiation-Reaction in Relativistic Laser Acceleration
摘要：
本文的目标是双重的：探索经典电荷的电磁力在自然单位的统一水平的响应，并建立一个标准，确定相关的辐射反应效应是可检测的物理参数。在追求这个目标，朗道-Lifshitz方程解析求解任意（横向）电磁脉冲。通过对Landau-Lifshitz方程和洛伦兹力方程下的线极化脉冲中电子辐射发射的比较研究，揭示了辐射-反应主导的机制，即辐射-反应效应克服了外场的影响。详细研究了相对论电子被反向传播电磁脉冲减速的情况。进一步证明了当电子经历单位阶加速度时，洛伦兹力方程、Landau-Lifshitz方程和Lorentz-Abraham-Dirac方程的动力学都导致了不同的辐射发射，这些辐射发射在实验中是可以区分的.最后，我们的分析和数值结果与文献中出现的那些进行了比较。
英文摘要：
The goal of this paper is twofold: to explore the response of classical charges to electromagnetic force at the level of unity in natural units and to establish a criterion that determines physical parameters for which the related radiation-reaction effects are detectable. In pursuit of this goal, the Landau-Lifshitz equation is solved analytically for an arbitrary (transverse) electromagnetic pulse. A comparative study of the radiation emission of an electron in a linearly polarized pulse for the Landau-Lifshitz equation and for the Lorentz force equation reveals the radiation-reaction dominated regime, in which radiation-reaction effects overcome the influence of the external fields. The case of a relativistic electron that is slowed down by a counter propagating electromagnetic pulse is studied in detail. We further show that when the electron experiences acceleration of order unity, the dynamics of the Lorentz force equation, the Landau-Lifshitz equation and the Lorentz-Abraham-Dirac equation all result in different radiation emission that could be distinguished in experiment. Finally, our analytic and numerical results are compared with those appearing in the literature.
