  1. 30. From one to many particles: Coherent emission and radiation reaction
    Matteo Tamburini (Max Planck Institute for Nuclear Physics)
    30/08/2024, 09:00

    The trajectories of relativistic particles in an intense electromagnetic field can be described by the Landau-Lifshitz equation, where the effect of radiation emission is accounted for via a self-force, and interparticle fields are often neglected as an approximation. Yet, the inclusion of interparticle fields is necessary to ensure energy-momentum conservation, particularly during coherent...

  2. 25. Strong-field QED effects in pulsar emission
    Dong-Hoon Kim (Seoul National University)
    30/08/2024, 09:25

    Highly magnetized neutron stars have quantum refraction effects on pulsar emission due to the non-
    linearity of the quantum electrodynamics (QED) action. In this context, we investigate the strong-field
    QED effects on the following properties in pulsar emission: (i) the propagation and polarization
    vectors, (ii) the polarization states. With regard to (i), we determine the leading-order...

  3. 45. Extending limits of QED-PIC simulations
    Arkady Gonoskov (University of Gothenburg)
    30/08/2024, 10:10

    Despite some methodological limitations, particle-in-cell simulations can be used to analyze laser-driven QED cascades and dynamics of the emergent QED plasmas. These processes, however, can quickly run into extreme regimes in terms of number of particles and their density causing extraordinary computational demands. We discuss possibilities to overcome some key limitations of the PIC method...

  4. 34. A path towards seeding QED cascades using direct laser acceleration
    Prof. Marija Vranic (Instituto de Plasmas e Fusão Nuclear, Instituto Superior Técnico-Universidade de Lisboa, Lisbon, Portugal)
    30/08/2024, 10:35

    Lasers at moderate intensities propagating through a plasma waveguide have demonstrated the potential for generating high-frequency radiation [1] as well as high-charge (>100 nC) electron beams [2] via direct laser acceleration (DLA). Such electron beams in a strong field background can emit multi-MeV photons, which have many potential applications in laboratory astrophysics, photonuclear...
