Weiwei Li has successfully defended his PhD thesis on “Petahertz strong-field light–matter interaction in nanomaterials”!
In his PhD research under the supervision of Prof. Matthias Kling, Weiwei investigated ultrafast electronic dynamics and strong-field light-matter interactions in solid-state nanomaterials, building upon key techniques developed in attosecond science, such as the ambient petahertz field sampling and high-harmonics spectroscopy. In particular, he was able to resolve the femtosecond-scale dephasing dynamics of the excited plasmon mode and optical mode in both isolated and coupled nanosystems in the time domain. In addition, his study on Brunel-type harmonic generation in organic semiconductors revealed an enhancement due to a resonant transition process in the molecules.
Congratulations!
