Abstract

The next generation of lasers will access intensities above 10^23 W/cm^2. When plasmas or relativistic electron beams interact with these lasers, energy loss due to radiation emission, or quantum effects such as electron-positron pair creation become important for their dynamics. Repeated occurrence of pair creation can induce a so-called “QED cascade”, that generates an exponentially rising number of particles. This allows for creating exotic plasmas that are a mix of electrons, ions, positrons, energetic photons and intense background fields.

Extreme laser-plasma interactions can be explored to form optical traps, create & accelerate particles and produce novel radiation sources. I will introduce a QED module coupled with the massively particle-in-cell framework OSIRIS that allows studying nonlinear plasma dynamics in the transition from the classical to the quantum-dominated regime of interaction. Special initiatives to preserve scalability on supercomputers will be presented.

About the Speaker

m vranicMarija Vranic obtained her MSc degree from University of Belgrade, Serbia and her PhD at Instituto Superior Tecnico in Lisbon, Portugal. After her PhD, she worked in the Extreme Light Infrastructure in Prague, Czech Republic, and then returned to Portugal. Her research is focused on plasmas in extreme conditions, where quantum effects can affect the collective plasma dynamics. She combines analytical theory and massively parallel computer simulations to perform the studies relevant for state-of-the-art and near-future laser experiments using the most intense lasers in the world.

Marija is a winner of the international John Dawson PhD thesis prize (best PhD thesis worldwide in the field of plasma-based accelerators), the IBM Scientific Prize and Ada Lovelace PRACE award
