Electronic correlation in atoms and molecules studied time-resolved with synchronized visible/IR and X-ray pulses

Markus Drescher, Michael Meyer

The evolution of correlated interactions between two or more electrons as a response to the deep excitation of a larger electron system is studied in their interplay with structural changes in a molecule occurring on a similar time scale. A joint focus with A2, A3, A4, A6, A7 and C7 on molecules with shared electrons will help disclosing the role of delocalized charge in locally excited systems. Control mechanisms utilizing multi-color light fields of defined polarization and timing will be explored to transfer electronic order to molecular fragments and protect molecules from being excited with ionizing radiation.
