R&D activity

The primary aim of the Ultrafast Nanoscience Group is to study few-femtosecond dynamics of plasmonic field enhancement on different systems. We demonstrated that we can probe the nanoplasmonic field enhancement in any metallic surface environment with simple photoelectron spectroscopy (Rácz, Pápa et al., Nano Lett. 2017). We continue experiments to explore the coupling mechanism between different types of plasmons. Meanwhile, experiments focusing on the spatial behavior of the photoemitted electrons are being prepared, which will provide insight into the spatial distribution of plasmonic near fields. Performing these measurements in a pump-probe manner will later reveal the time evolution of the excited plasmon field as well. The combination of the tools available at ELI will boost the deeper understanding of the evolution of plasmonic fields both in time and space, shedding light on unknown features of collective electron dnyamics.
