The generation and characterization of attosecond laser pulses has been significantly advanced in recent years and two major tools are now at hand that can be used to explore ultrafast physics.
The first is the ability to control electronic motion via waveform controlled laser fields. The second is the availability of single attosecond pulses that can be used to probe electronic motion in real-time. We want to use these tools to study collective electronic dynamics, which are of particular importance for the optical response of nanoparticles. These materials are of huge fundamental interest and have wide applications ranging from markers in medicine and biology over catalysts in chemistry to quantum computers.
The motivation for studies on nanoparticles is r elated to the possibility of tailoring their dynamical behaviour on the basis of size and shape. For the first time, we will explore electron dynamics in nanoparticles with sub-femtosecond time resolution. This way, we can gain information on the collective electronic properties of these materials on the timescale on which they occur in nature. Our work can have a huge impact on the development of nanoplasmonic devices.
The proposed project will help the applicant to successfully reintegrate into academics and form the basis for his career as an independent scientist and group leader in attosecond science. The proposal will also contribute to keeping European research at the forefront in this quickly evolving scientific field.
