Explore the quantum electrodynamic phenomenon of pair production through photon-photon collisions in laser-irradiated plasma environments in this 45-minute conference talk. Delve into the fundamental physics of how high-energy photons interact to create electron-positron pairs when intense laser fields interact with plasma, a process crucial for understanding extreme astrophysical environments around black holes and neutron stars. Learn about the theoretical framework governing these quantum field effects in relativistic plasma conditions and discover how laboratory laser-plasma experiments can simulate and study processes that occur naturally in the most energetic regions of the universe. Examine the role of this mechanism in the broader context of extreme plasma physics, including its relevance to magnetic reconnection, shock formation, and other nonlinear plasma processes under relativistic conditions. Gain insights into cutting-edge research that bridges laboratory plasma physics with high-energy astrophysics, contributing to our understanding of phenomena such as Fast Radio Bursts and the behavior of matter near event horizons of accreting black holes.
