Program | Abstract: Recent advances in the generation of well-characterized sub-femtosecond laser pulses have opened up unprecedented opportunities for real-time observation of electronic dynamics in atoms, molecules and solids. It is now possible to map out the evolution of the electronic wavepacket initiated by an ultrashort pulse. One of the major challenges still is to identify and to understand electronic correlations in the time domain. Unlike well established correlation effects in the groundstate such dynamical correlations have remained elusive until recently. Ab initio simulations of the many- electron Schrödinger equation allow now to decribe the electronic response to ultrashort pulses beyond the mean field or single particle Level and to help identifying dynamical correlation effects in the experiment. We will illustrate recent advances with prototypical examples including the time-resolved build-up of Fano resonances and the time delay of correlation satellites in helium. |
