  1. 21. Quantum Vacuum Simulation Algorithm and Code (QVSP)
    Baris Ölmez, Andreas Maximilian Lindner (LMU Munich)
    27.04.21, 13:00

    A numerical scheme for solving the nonlinear Heisenberg-Euler equation in up to 3 spatial dimensions plus time is derived and its properties are discussed. This "quantum vacuum simulation algorithm" is tested against a set of already known analytical results and its power to go beyond analytically solvable scenarios is shown.

  2. 22. Vacuum birefringence and diffraction at XFEL: from analytical estimates to optimal parameters
    Elena Mosman (Tomsk Polytechnic University)
    27.04.21, 13:30

    We study vacuum birefringence and x-ray photon scattering in the head-on collision of x-ray free electron and high-intensity laser pulses. Resorting to analytical approximations for the numbers of attainable signal photons, we analyze the behavior of the phenomenon under the variation of various experimental key-parameters and provide new analytical scalings. Our optimized approximations...

  3. 28. Numerical Simulation of Colliding Laser Pulses
    Andreas Maximilian Lindner (LMU Munich), Baris Ölmez
    27.04.21, 14:00

    The nonlinear optical properties of colliding high field laser pulses in HE weak field approximation is investigated numerically. The numerical approach is detailed.
