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…
Semiclassical picture for electron-positron photoproduction in strong laser fields
Sebastian Meuren, Christoph H. Keitel, Antonino Di Piazza
The nonlinear Breit-Wheeler process is studied in the presence of strong and short laser pulses. We show that for a relativistically intense plane-wave laser field many features of…
Optimized Training for Net Energy Maximization in Multi-Antenna Wireless Energy Transfer over Frequency-Selective Channel
Yong Zeng, Rui Zhang
This paper studies the training design problem for multiple-input single-output (MISO) wireless energy transfer (WET) systems in frequency-selective channels, where the frequency-d…
