We illustrate how our recent light-front approach simplifies relativistic electrodynamics with an electromagnetic (EM) field F that is the sum of a (even very intense) plane travelling wave F_t (ct-z) and a static part F_s (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.)

Abstract
We illustrate how our recent light-front approach simplifies relativistic electrodynamics with an electromagnetic (EM) field F that is the sum of a (even very intense) plane travelling wave F_t (ct-z) and a static part F_s (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.)I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
