AG Faßhauer: Theoretical Dynamics
The group of Elke Faßhauer is interested in ultrafast energy and electron transfer processes, their characteristics and the methods used to described them. This includes their initiations by excitation and ionization, their time evolution as well as their time-resolved measurement. A few examples are:
Time-resolved spectroscopy where they are building time-dependent theoretical models that describes the Interatomic Coulombic Decay and allow to gain time-resolved information about electronic decay processes by proposing new experiments as well as to interpret experimental results.
Electronic decay processes in large systems, which characteristics are influenced by the environment. For this purpose they have developed the program HARDRoC, which is used to study the effect of the environment on Interparticle Coulombic Decay processes. Its development allowed to increase the system size from 13 atoms to several thousand atoms.
Many-body quantum dynamics / Trapped Fermions Escape: In this work a efficient implementation of a theoretical method is presented, which allows to study the motion of fermions and how they escape in an exact way.
Relativistic quantum chemistry, where they investigate the influence of relativistic effects with a focus on lifetimes of electronic decay processes and in connection to ultrafast spectroscopy.
