Laser absorption via QED cascades in counter propagating laser pulses
Thomas Grismayer, Marija Vranic, Joana L. Martins +2
A model for laser light absorption in electron-positron plasmas self-consistently created via QED cascades is described. The laser energy is mainly absorbed due to hard photon emis…
Seeded QED cascades in counter propagating laser pulses
Thomas Grismayer, Marija Vranic, Joana L Martins +2
The growth rates of seeded QED cascades in counter propagating lasers are calculated with first principles 2D/3D QED-PIC simulations. The dependence of the growth rate on laser pol…
Quantum radiation reaction in head-on laser-electron beam interaction
Marija Vranic, Thomas Grismayer, Ricardo A. Fonseca +1
In this paper, we investigate the evolution of the energy spread and the divergence of electron beams while they interact with different laser pulses at intensities where quantum e…
Modelling radiation emission in the transition from the classical to the quantum regime
J. L. Martins, M. Vranic, T. Grismayer +3
An emissivity formula is derived using the generalised Fermi-Weizacker-Williams method of virtual photons which accounts for the recoil the charged particle experiences as it emits…
Slow down of a globally neutral relativistic beam shearing the vacuum
E. P. Alves, T. Grismayer, M. G. Silveirinha +2
The microphysics of relativistic collisionless sheared flows is investigated in a configuration consisting of a globally neutral, relativistic beam streaming through a hol…
Transverse electron-scale instability in relativistic shear flows
E. P. Alves, T. Grismayer, R. A. Fonseca +1
Electron-scale surface waves are shown to be unstable in the transverse plane of a shear flow in an initially unmagnetized plasma, unlike in the (magneto)hydrodynamics case. It is…
Spatial-temporal evolution of the current filamentation instability
V. B. Pathak, T. Grismayer, A. Stockem +2
The spatial-temporal evolution of the purely transverse current filamentation instability is analyzed by deriving a single partial differential equation for the instability and obt…
