P21 - Doppler-Boosted Lasers: A New Path to Extreme QED Pair Plasmas in Light-Matter and Light-Quantum Vacuum Interactions
DescriptionHow does light interact with matter or the quantum vacuum at intensities where the physics is governed by Quantum Electrodynamics (QED)? What are the properties of the QED electron-positron pair plasma produced in those interactions? Can the probing of this plasma help address open problems in quantum field theory and astrophysics? Answering these questions requires light intensities far beyond the ones achieved by the most intense PetaWatt (PW) laser on earth. To break this barrier, we recently proposed new schemes to considerably ‘boost’ the intensity of present lasers by Doppler effect employing physical systems called ‘relativistic plasma mirrors’. In this poster, we will first introduce the novel schemes that have been developed at Commissariat à l'Energie Atomique (CEA) to probe novel QED plasma states in light-matter and light-quantum vacuum interactions. We will then present the exascale simulation tools that we have co-developed with the Lawrence Berkeley National Lab (LBNL) to understand the basic physics of these QED plasmas and help identify clear SF-QED signatures that shall be observed in experiments. Our simulations will be key to stimulate, design and guide experiments intended to detect these signatures at PW laser facilities.
