The group focuses on the exploration of the particle dynamics in the realm of strong and critical Coulomb and photon fields with particle emphasis on Quantum Electrodynamics. For this purpose highly charged ions and strong laser fields and their combination are particularly well suited but require the development of dedicated diagnostics and instrumentation. As examples, within our experimental campaigns various x-ray detection systems such as 2D/3D position-sensitive and energy-dispersive detectors, crystal spectrometers, x-ray CCDs, novel x-ray polarimeters, and micro-calorimeters are getting developed and used as well as ion sources, storage rings, and traps to study ions in intense laser light.
Prof. Stöhlker's research interests are focused on electron dynamics in strong and even extreme fields, with particular emphasis of the effects of quantum electrodynamics (QED):
Prof. Stöhlker's teaching is focused on the physics of simple atomic systems, including the atomic structure, atomic collisions, and fundamental aspects such as QED and parity violation. He gives courses and seminars in:
Prof. Stöhlker runs sophisticated setups for photon, x-ray, electron, and ion spectroscopy which are used for the studies at storage rings, traps and synchrotrons, including:
