论文摘要
我们表明，基于10个PW级激光器的$λ^{3} $配置在$λ^{3} $配置中的激光 - 电子碰撞的全光配置提供了一个可行的平台，用于达到参数范围，其中在强的外部电气电磁场中扰动QED。该案例被称为非驾驶QED的情况；从实验的角度来看，这种参数范围是一个有趣的目标，因为可能表现出高度辐射粒子与强电磁场的相互作用的新物理学。我们表明，具有高于50 GEV的初始能量的电子可以达到强场区域。我们的理论考虑与三维粒子中的模拟一致。虽然增加电子能量会增加经历强场区域的电子数量，但在电子能量超过最佳值时，强场中光子发射辐射校正的可观察到的特征预计将逐渐消失。确定了电子能量的阈值，并提供了实现QED非扰动极限的参数。
We show that an all-optical configuration of the laser-electron collision in the $λ^{3}$ configuration based on 10 PW-class lasers presents a viable platform for reaching the range of parameters where a perturbative QED in strong external electromagnetic field breaks. This case is contingently referred to as a case of the nonperturbative QED; and this range of parameters is the intriguing goal from an experimental point of view because of a possible manifestation of a new physics of the interaction of a highly radiating particle with a strong electromagnetic field. We show that the strong field region can be reached by the electrons having the initial energy higher than 50 GeV. Our theoretical considerations are in agreement with three-dimensional particle-in-cell simulations. While increasing of the electron energy raises the number of electrons experiencing the strong field region, the observable signature of photon emission radiative correction in the strong field is expected to fade out when the electron energy surpasses the optimal value. This threshold of electron energy is identified and the parameters for achieving the nonperturbative limit of QED are provided.
