COLLOQUIUM: In Silico Plasmas Under Extreme Intensities
Intense laser and particle beams can be focused down to intensities in excess of 10^23 W/cm^2. Similar intensities are also present in extreme astrophysical scenarios. Under these conditions, the interaction of these intense beams and fields with plasmas is very rich, permeated by collective processes, relativistic nonlinearities and strong field physics. The complexity of these scenarios can only be grasped resorting to large scale numerical simulations. Advanced multi-scale models combined with massively parallel high performance computing are driving new discoveries. I will review the recent developments in multi-scale models and some of the recent results from the in silico exploration of extreme plasma physics scenarios, ranging from collisionless shocks driven by intense beams, to the dynamics of electron-positron fireballs, or to the physics and the dynamics of intense fields when QED starts to be relevant. I will also discuss how the next generation of exaflop supercomputers will determine the new models and the impact of computational plasma sciences.
