Congratulations to Weiwei Li!

Weiwei Li has successfully his PhD thesis in the group of Prof. Matthias Kling.

We are happy to share that Weiwei Li has successfully defended his PhD thesis on “Petahertz strong-field light–matter interaction in nanomaterials”!

Recent advances in attosecond physics have marked a significant transition from studies in gas-phase atoms and molecules to those in condensed matter, where intrinsic periodicity and complex structures provide a fertile platform for uncovering novel phenomena and enabling transformative applications.

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. And his study on Brunel-type harmonic generation in organic semiconductors has revealed an enhancement due to a resonant transition process in the molecules.

Congratulations, dear Weiwei, and all the best for your future!
