Quasistatic modeling of ultrarelativistic beam-plasma instabilities
P. San Miguel Claveria, L. Gremillet, X. Davoine +5
Relativistic particle beams propagating through dense ambient plasmas are susceptible to streaming instabilities that can govern the system dynamics in various astrophysical and la…
Modeling ultrarelativistic streaming plasma instabilities under the quasistatic approximation
P. San Miguel Claveria, Q. Labro, X. Davoine +5
Plasma streaming instabilities excited by relativistic charged particle beams play a pivotal role in astrophysical and laboratory environments. Their numerical study, however, is c…
Strong-field focusing of high-energy particles in beam-multifoil collisions
Aimé Matheron, Doug Storey, Max F. Gilljohann +25
Extreme beams of charged particles and photons, reaching ultrahigh densities or producing intense gamma-ray bursts, are central to accelerator physics, laboratory astrophysics, and…
Simulating vacuum birefringence with a diffractive beam propagation code
Aimé Matheron, Michal Å mÃd, Matt Zepf +1
Ninety years after their prediction, quantum vacuum nonlinearities in macroscopic electromagnetic fields still await a direct experimental verification in the laboratory. A particu…
Decoupling acceleration and wiggling in a laser-produced Betatron source
Julien Gautier, Igor Andriyash, Andreas Döpp +11
Betatron radiation is produced in Laser Plasma Accelerators when the electrons are accelerated and simultaneously wiggle across the propagation axis. The mechanisms of electron acc…
The Darkfield Approach to Measuring Vacuum Birefringence and Light-by-Light Couplings -- A Proof-of-Principle Experiment
Michal SmÃd, Pooyan Khademi, Carsten Bähtz +29
Vacuum fluctuations give rise to effective nonlinear interactions between electromagnetic fields. These generically modify the characteristics of light traversing a strong-field re…
