Injection and Trapping of Tunnel Ionized Electrons into Laser Produced Wakes
TL;DR: A method, which utilizes the large difference in ionization potentials between successive ionization states of trace atoms, for injecting electrons into a laser-driven wakefield is presented, and a mixture of helium and trace amounts of nitrogen gas was used.

TL;DR: A modified event generator is proposed that precisely models the entire spectrum of incoherent particle emission without any low-energy cutoff, and which imposes close to the weakest possible demands on the numerical time step.

Energy partition, γ-ray emission, and radiation reaction in the near-quantum electrodynamical regime of laser-plasma interaction
TL;DR: In this paper, the energy partition in the laser-plasma system was investigated using three-dimensional particle-in-cell simulations which include a quantum electrodynamics model for the γ-photons emission, the corresponding RR force and electron-positron pair creation.

Particle merging algorithm for PIC codes
Marija Vranic,Thomas Grismayer,Joana Luis Martins,Ricardo Fonseca,Ricardo Fonseca,Luis O. Silva +5 more
TL;DR: An alternative algorithm based on the coalescence of N massive or massless particles, considered to be close enough in phase space, into two new macro-particles is described, showing in addition to the conservation of local quantities, the good reproducibility of the particle distributions.

Physics of laser-driven plasma-based electron accelerators
TL;DR: In this paper, the basic physics of laser pulse evolution in underdense plasmas is also reviewed, including the propagation, self-focusing, and guiding of laser pulses in uniform density channels and with preformed density channels.
Tunnel ionization of complex atoms and of atomic ions in an altemating electromagnetic field
