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...
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...
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...
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...
