Contemporary advances in ultra-intense laser facilities have driven the recent surge of interest in the collective behaviour of charged matter in extreme conditions, and a particularly vexing topic in that context concerns the coupling of an electron to its own radiation field. In most practical cases, the Lorentz force on an electron, due to an applied electromagnetic field, is considerably...

Plasma acceleration exploits extreme electric fields created in a plasma by high-current beams or high-intensity laser pulses, to accelerate charged particles. In current studies we explore prospects for beam-driven plasma acceleration within FLASHForward project at DESY, by means of 3D particle-in-cell simulations with the code OSIRIS. In particular, various techniques of injecting particles...

The intensity of short pulse lasers is now sufficiently high that the dynamics of energetic electrons in these fields is dominated by quantum radiation reaction. We present simulations of an experiment that uses a laser wakefield to drive GeV electrons into a counterpropagating laser pulse of intensity 10^{22} Wcm^{-2}. The stochastic nature of photon emission leads to broadening of the...

Stimulated Raman scattering of an ultra-intense laser pulse in plasmas is studied by pertur- batively including the leading order term of the Landau-Lifshitz radiation reaction force in the equation of motion for plasma electrons. In this approximation, radiation reaction force causes phase lag in nonlinear current densities that drive the two Raman sidebands (anti-Stokes and Stokes waves),...
