Coherent hole dynamics in attosecond molecular photo-ionization

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
