SUMMARY:P21 - Doppler-Boosted Lasers: A New Path to Extreme QED Pair Plasm
 as in Light-Matter and Light-Quantum Vacuum Interactions
DESCRIPTION:Poster\n\nHenri Vincenti, Luca Fedeli, Neil Zaim, Antonin Sain
 te-Marie, Pierre Bartoli, and Thomas Clark (CEA) and Jean-Luc Vay and Axel
  Huebl (Lawrence Berkeley National Laboratory)\n\nHow does light interact 
 with matter or the quantum vacuum at intensities where the physics is gove
 rned by Quantum Electrodynamics (QED)? What are the properties of the QED 
 electron-positron pair plasma produced in those interactions? Can the prob
 ing of this plasma help address open problems in quantum field theory and 
 astrophysics? Answering these questions requires light intensities far bey
 ond the ones achieved by the most intense PetaWatt (PW) laser on earth. To
  break this barrier, we recently proposed new schemes to considerably ‘boo
 st’ the intensity of present lasers by Doppler effect employing physical s
 ystems 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 an
 d light-quantum vacuum interactions. We will then present the exascale sim
 ulation tools that we have co-developed with the Lawrence Berkeley Nationa
 l Lab (LBNL) to understand the basic physics of these QED plasmas and help
  identify clear SF-QED signatures that shall be observed in experiments. O
 ur simulations will be key to stimulate, design and guide experiments inte
 nded to detect these signatures at PW laser facilities.
