We are looking for for a postdoctoral researcher (2 years) with a background in quantum optics or strong field physics and a strong interest in interdisciplinary research. The key aim of the project “Strong field physics with nonclassical light fields” is to investigate the interaction of strong, nonclassical light fields with matter. The successful applicant is expected to apply and develop numerical and analytical methods of theoretical quantum optics to describe light-matter interactions with large photon numbers.
