Topic: Extreme laser-matter interactions: kinetic modeling of relativistic, ultrarelativistic and radiation dominated plasma

Abstract: Plasma appears in the Universe in a staggering variety of forms, which are shaped by the collective dynamics of electromagnetic fields and charged particles, occurring on timescales that can be much shorter than those of the binary processes among individual charges. This highly non equilibrium matter, dominated by nonlinearities, can produce unprecedented large energy densities on small scales in the laboratory and on huge spatial scales in the Universe. The recent developments in the generation of laser pulses with ultra-high power have made it possible to obtain and to study macroscopic amounts of relativistic plasma in relatively compact size experiments and opened the way to new advances in fields that range from nonlinear dynamics and nonlinear relativistic optics to (i) novel powerful radiation sources at high energy, (ii) alternative particle acceleration techniques, (iii) high energy astrophysics, including relativistic shocks, cosmic ray physics and radiative magnetic reconnection, and finally, (iv) plasma dominated by QED effects, such as quantum recoil and creation of electron-positron pairs. In this talk I will report about the recent achievements and developments in the novel laser-plasma based particle acceleration techniques, radiation pressure acceleration of ion beams in view of possible medical and technological applications, and discuss expectations based on large scale simulations.
