Title: Plasm a dynamics in extreme fields: challenges and opportunities

Abstract: The next gene ration of lasers will access intensities above 10^23 W/cm^2. When plasmas or relativistic electron beams interact with these lasers\, energy loss du e to radiation emission\, or quantum effects such as electron-positron pai r creation become important for their dynamics. Repeated occurrence of pai r creation can induce a so-called “QED cascade”\, that generates an ex ponentially rising number of particles. This allows for creating exotic pl asmas that are a mix of electrons\, ions\, positrons\, energetic photons a nd intense background fields. Extreme laser-plasma interactions can be exp lored to form optical traps\, create&\;accelerate particles and produce novel radiation sources. I will introduce a QED module coupled with the p article-in-cell framework OSIRIS that allows studying nonlinear plasma dyn amics in the transition from the classical to the quantum-dominated regime of interaction. Studies relevant for (near) future experiments will be di scussed.
