Abstract: Laser-driven relativistic quantum dynamics and the key features of quantum vacuum are introduced [1]. Applications such as the characterization of extreme laser pulses are presented [2]. Then, emphasis is placed on situations where the influence of vacuum fluctuations is shown to become observable with present laser facilities or those under construction [3]. In the following, pair production is investigated in strong laser fields, especially with the aid of other injected particles [4]. Then, spin effects for Kapitza-Dirac scattering [5] and the role of radiative reaction [6] for single particles and in plasmas are presented.

Finally, mono energetic ion acceleration with chirped laser pulses is discussed [7] followed by applications of XFEL-driven ions [8] and nuclei [9], and in case of sufficient time, a recent scheme for laser-control of positronium dynamics [10].
