Abstract: | Abstract
Molecular photo-ionization by attosecond pulses leads to creation of coherent superpositions of ionic states and as a result to coherent dynamics of the electron hole. The temporal extent of this coherent dynamics, that can be seen as a migration of the electron hole across the molecular volume, is limited by decoherence stemming from the zero-point energy of the nuclear vibrations, the nuclear motion itself, as well as by the electronic decay of the ionic wavepacket components above the double ionization threshold. In this presentation, I will discuss the theoretical interpretation of our recent hole migration experiments performed at the LCLS and FLASH X-ray free electron laser facilities, as well as the many-electron theoretical tools that allow us to gain insight into the mechanisms of the onset and decay of the coherent hole dynamics
