Quantum dynamics of nuclear many-body systems driven by an XFEL — •Miriam Gerharz and Jörg Evers — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

Ensembles of Mössbauer nuclei form a promising platform for quantum optics in extreme parameter regimes because of their narrow transitions in the hard x-ray regime. These narrow transitions feature long lifetimes, which results in the system being essentially decoherence free. However, because of those narrow resonances at synchrotrons on average there is less than one resonant photon per pulse. This situation has recently changed with first experiments at X-ray free electron lasers (XFEL), where there are up to hundreds of resonant photons per pulse, such that qualitatively new regimes of higher nuclear excitations can be explored. Here we present recent progress in the theoretical modelling of the dissipative nuclear many-body dynamics after XFEL excitation.
