Thomas Hansen’s Ph.D. study has centered around high-harmonic generation from strongly correlated systems. High-harmonic generation is a process used to generate ultrashort laser pulses, which are important to measurements with time resolution at the ultrashort attosecond timescale. High-harmonic generation from strongly correlated systems is especially interesting as the correlation has been shown to increase the intensity of the generated pulses, and the generation process can tell us about the dynamics in the materials, which is otherwise difficult to gain insight into.

The results I have obtained have contributed to our understanding of high-harmonic generation from and driven dynamics in strongly correlated systems.

The PhD study was completed at the Department of Physics and Astronomy, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
