Ultrafast Dynamics in Nanoscale Systems

Our goal is to understand physical phenomena in nanosystems and to explore their application in technologies that have yet to be imagined. For this we develop and use optical and optoelectronic techniques with ultrashort temporal and ultrasmall spatial resolution.  

Ultrafast plus ultrasmall equals great prospects

The ultrafast phenomena that take place at the nanoscale have far-reaching implications for materials and systems and can lead novel applications in fields such as thermal management, light harvesting, photodetection, data communication and quantum technologies. Currently, one of the main material systems under investigation in the UDNS group is that of quantum materials, in particular, two-dimensional layered materials and hybrid Van der Waals heterostructures. The group studies the exciting interplay between different carriers of energy/heat/information in these systems, such as photons, electrons, phonons, spins and other (quasi-)particles. The research is also branching out to one-dimensional systems.
