论文摘要
我们说明了我们最近的轻型方法如何用电磁（EM）字段$ f^{μν} $简化相对论电动力学，这是A（甚至非常激烈的）飞行波动$ f_t^{μν}（ct \！ - \！Z）$和静态部分$ f_s $ f_s $ f_s^y的总和。它采用类似光的坐标$ξ= ct \！ - \！z $而不是时间$ t $作为自变量。这可以应用于几种极端加速的情况，无论是在真空和冷稀释的血浆中，都被非常短而强烈的激光脉冲击中（弹弓效应，等离子体波和激光唤醒场加速等）
We illustrate how our recent light-front approach simplifies relativistic electrodynamics with an electromagnetic (EM) field $F^{μν}$ that is the sum of a (even very intense) plane travelling wave $F_t^{μν}(ct\!-\!z)$ and a static part $F_s^{μν}(x,y,z)$; it adopts the light-like coordinate $ξ=ct\!-\!z$ instead of time $t$ as an independent variable. This can be applied to several cases of extreme acceleration, both in vacuum and in a cold diluted plasma hit by a very short and intense laser pulse (slingshot effect, plasma wave-breaking and laser wake-field acceleration, etc.)
