Attosecond Electron Dynamics in Isolated Nanostructures
With the application of waveform-controlled laser pulses to nanoscale materials the new field of attosecond nanophysics has emerged. Laser waveforms of well-defined shape have proven to be an essential tool for controlling electronic strong-field processes in nanoscale systems such as nanoparticles, nanotips, and surface assembled nanostructures with attosecond resolution. In the talk our recent results on studies of attosecond electron dynamics in isolated nanoparticles and nanoclusters will be presented. Waveform-controlled photoemission process in tailored near-fields of dielectric nanoparticles was studied in the intensity regime where the nonlinear charge interaction significantly contributes to the electron acceleration. Application of attosecond streaking technique to isolated nanoparticles, where attosecond XUV pulse induces photoemission process and a delayed few-cycle VIS-NIR pulse maps the electron dynamics, allowed real-time access to electron scattering in dielectric material.
