The University of Kassel is a modern and growing University with round about 23.000 students. It has an extraordinary wide section with expertise of nature, technique, culture and society.

In the subject area Mathematics and natural sciences, Institute of Physics – research group Structural Molecular Dynamics (Prof. Dr. Jochen Mikosch), the following job vacancy is to be filled as soon as possible:

Research Assistant (m/f/d), EG 13 TV-H, temorary, full time (currently 40 working hours)

Closes: 21.06.2023
Date of Hire: as soon as possible
Reference: 36198
The position in initially until 31.05.2026 according to § 2 Abs. 1 WissZeitVG.

In our group we investigate the evolving structure in molecular and chemical dynamics on ultrafast timescales with methods adapted from attosecond (10-18s) science. Processes on these unprecedented timescales represent one of the major new frontiers in contemporary physics. We are offering a PhD project in physics dedicated to the experimental investigation of laser-driven electron rescattering in molecules. In this process, a single electron is extracted from a molecule by laser-induced tunnel ionization, accelerated in the strong infrared field of the laser and driven back to its origin within a fraction of the optical cycle, where it can elastically scatter. This self-imaged of a molecule by one of its own electrons is one of the most promising emerging techniques to make the molecular movie - capable of recording structural changes in molecules, for instance during a chemical reaction, in real time. The position is fully funded by the Deutsche Forschungsgemeinschaft (DFG). The experimental work involves a state-of-the-art Reaction Microscope to detect the momentum of photoions and -electrons in coincidence.
