High-energy quantum physics with extreme laser pulses

The talk starts with an introduction into the strong-field QED applicable for the collision of a high-energy electron beam with an ultra-strong laser pulse. For this purpose, radiative reaction, spin dynamics and pair production are discussed. Emphasis on recent progress will be given on the generation and polarization of high-energy electron, positron and gamma-ray beams, plasma diagnostics, and tests of fundamental physics. Also, nuclear quantum control is considered and an outlook on attractive feasible experiments in the light of upcoming facilities is given.
