Generation of a neutral, high-density electron-positron plasma in the laboratory
G. Sarri, K. Poder, J. Cole +17
We report on the laser-driven generation of purely neutral, relativistic electron-positron pair plasmas. The overall charge neutrality, high average Lorentz factor ($γ_{e/p} \appro…
Ultrarelativistic electron states in a general background electromagnetic field
A. Di Piazza
The feasibility of obtaining exact analytical results in the realm of QED in the presence of a background electromagnetic field is almost exclusively limited to a few tractable cas…
Axion-induced birefringence effects in laser driven nonlinear vacuum interaction
Selym Villalba-Chávez, Antonino Di Piazza
The propagation of a probe electromagnetic field through a counterpropagating strong plane wave is investigated. The effects of the electromagnetic field-(pseudo)scalar axion field…
Electron dynamics controlled via self-interaction
Matteo Tamburini, Christoph H. Keitel, Antonino Di Piazza
The dynamics of an electron in a strong laser field can be significantly altered by radiation reaction. This usually results in a strongly damped motion, with the electron losing a…
A table-top laser-based source of femtosecond, collimated, ultra-relativistic positron beams
G. Sarri, W. Schumaker, A. Di Piazza +13
The generation of ultra-relativistic positron beams with short duration ( fs), small divergence ( mrad), and high density ($n_{e^+} \simeq 10^{14…
Polarization operator for plane-wave background fields
S. Meuren, C. H. Keitel, A. Di Piazza
We derive an alternative representation of the leading-order contribution to the polarization operator in strong-field quantum electrodynamics with a plane-wave electromagnetic bac…
On refractive processes in strong laser field quantum electrodynamics
A. Di Piazza
Refractive processes in strong-field QED are pure quantum processes, which involve only external photons and the background electromagnetic field. We show analytically that such pr…
Stochasticity effects in quantum radiation reaction
N. Neitz, A. Di Piazza
When an ultrarelativistic electron beam collides with a sufficiently intense laser pulse, radiation-reaction effects can strongly alter the beam dynamics. In the realm of classical…
