Light-front approach to relativistic electrodynamics

Abstract

We illustrate how our recent light-front approach simplifies relativistic electrodynamics with an electromagnetic (EM) field $F^{\mu \nu }$ that is the sum of a (even very intense) plane travelling wave $F_t^{\mu \nu }(ct-z)$ and a static part $F_s^{\mu \nu }(x,y,z)$; it adopts the light-like coordinate $\xi =ct-z$ 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.)
