Effect of interparticle fields and radiation reaction on beam dynamics
Michael J. Quin, Antonino Di Piazza, Christoph H. Keitel +1
The dynamics of relativistic particles in an intense electromagnetic field can be described by the Landau-Lifshitz (LL) equation, where the adiation reaction (RR) is accounted for…
Charged particle beam transport in a flying focus pulse with orbital angular momentum
Martin Formanek, John P. Palastro, Marija Vranic +2
We demonstrate the capability of Flying Focus (FF) laser pulses with orbital angular momentum (OAM) to transversely confine ultra-relativistic charged particle bunches o…
Strong signature of one-loop self-energy in polarization resolved nonlinear Compton scattering
Yan-Fei Li, Yue-Yue Chen, K. Z. Hatsagortsyan +3
The polarization dynamics of electrons including multiple nonlinear Compton scattering during the interaction of a circularly-polarized ultraintense laser pulse with a counterpropa…
Nonlinear Thomson scattering with ponderomotive control
D. Ramsey, B. Malaca, A. Di Piazza +7
In nonlinear Thomson scattering, a relativistic electron reflects and re-radiates the photons of a laser pulse, converting optical light to x rays or beyond. While this extreme fre…
Laser-pulse-shape control of seeded QED cascades
Matteo Tamburini, Antonino Di Piazza, Christoph H. Keitel
QED cascades are complex avalanche processes of hard photon emission and electron-positron pair creation driven by ultra-strong electromagnetic fields. They play a fundamental role…
Investigation of classical radiation reaction with aligned crystals
A. Di Piazza, T. N. Wistisen, U. I. Uggerhøj
Classical radiation reaction is the effect of the electromagnetic field emitted by an accelerated electric charge on the motion of the charge itself. The self-consistent underlying…
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…
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…
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…
Plasma-Based Generation and Control of a Single Few-Cycle High-Energy Ultrahigh-Intensity Laser Pulse
M. Tamburini, A. Di Piazza, T. V. Liseykina +1
A laser-boosted relativistic solid-density paraboloidal foil is known to efficiently reflect and focus a counterpropagating laser pulse. Here we show that in the case of an ultrare…
Radiation Reaction Effects on Electron Nonlinear Dynamics and Ion Acceleration in Laser-solid Interaction
Matteo Tamburini, Francesco Pegoraro, Antonino Di Piazza +3
Radiation Reaction (RR) effects in the interaction of an ultra-intense laser pulse with a thin plasma foil are investigated analytically and by two-dimensional (2D3P) Particle-In-C…
Radiation Reaction Effects on Radiation Pressure Acceleration
M. Tamburini, F. Pegoraro, A. Di Piazza +2
Radiation reaction (RR) effects on the acceleration of a thin plasma foil by a superintense laser pulse in the radiation pressure dominated regime are investigated theoretically. A…
