Relativistic Quantum Dynamics in Strong Short Laser Pulses

Relativistic quantum dynamics of atoms and ions is introduced in intense laser fields [1]. Emphasis is placed here on allowing for relativistic recollisions via tailored attosecond pulses [2]. The feasibility of nuclear excitation dynamics is then shown to be realistic with XFEL light[3]. Quantum electrodynamical processes are investigated in extremely strong laser pulses, including nonlinearities of laser-driven vacuum [4]. Finally emphasis is placed on high-energy processes such as muon pair production from laser-driven positronium [5].
