The project proposed here addresses the imaging of strong-field processes in nanosystems using the coherent interaction with ultrashort electron pulses and their manipulation by tailored light fields. Specifically, we will employ and further extend two complementary techniques developed during the first funding period: (i) Quantum coherent inelastic scattering of high-energy electron pulses and attosecond electron pulse trains in an ultrafast transmission electron microscope and (ii) optical streaking in ultrafast point-projection microscopy. Both techniques combine nanoscale spatial probing with a sub-cycle temporal resolution, giving access to the mapping of local dynamics coherent transport phenomena in strongly inhomogeneous quantum systems. In particular, we will target light-driven dynamics in selected nanostructured solid-state systems, including plasmonic systems, nitrogen-vacancy centers and plasmon-exciton hybrid systems. Based on these model systems, we aim at establishing a universal experimental platform for the investigation of ultrafast dynamics in highly excited nanosystems.
