QED, radiative reaction and particle physics with strong laser-charged particle interaction — •Christoph H. Keitel, Antonino Di Piazza, Karen Z. Hatsagortsyan, and Carsten Müller — Max Planck Institute for Nuclear Physics, Theory Division, Heidelberg, Germany

Laser-driven relativistic quantum dynamics is discussed for bound and free electrons [1,2]. Applications such as the generation of harmonics and short pulses is discussed and compared to other means [3]. Then emphasis is placed on situations where the influence of vacuum fluctuations is shown to become observable with present facilities or those under construction, especially on the concept of a matterless double slit [4]. In the following, pair production is investigated in strong laser fields, especially with the aid of other injected particles [5]. Finally, the role of radiative reaction is presented for realistic situations, both in the classical and quantum regime [6].
