We begin with an introduction to state-of-the-art experiments that demonstrate interesting light-matter interactions, and applications of lasers in materials science. We particularly focus on how to probe the structure and dynamics of a material, and how ultrafast science enables the observation of multi-electron dynamics in atoms, molecules and solids. One exciting advancement in this field is high-harmonic generation (HHG) spectroscopy, a powerful tool to explore the interaction between molecules/materials and strong laser field, aiming to constitute an all-optical method to characterize materials. We will understand these processes in detail, and perform interesting hands-on simulations to find how HHG spectra can be calculated for small molecules. Results from students’ simulations will be shared FAIRly and the students will receive feedback on their approaches. Finally we learn to identify important parameters through convergence tests etc. Later-on we will have a lab-tour inside ELI-ALPS, to physically visit the laser facilities where such advanced experiments are actually performed, and learn ‘how’.
