Postdoc position (m/f/d) Development and Application of an Ultra-Bright Coherent Soft X-Ray Beamline

The Department of Physical Chemistry of Prof. Martin Wolf is seeking a highly motivated postdoctoral researcher to join our project focused on the realization of a bright tabletop coherent soft X-ray beamline, designed in collaboration with Prof. Jens Biegert (ICFO, Barcelona).

Our advanced multi-millijoule 2200 nm OPCPA system is operational, and the X-ray beamline has entered its final implementation phase offering the successful candidate an exciting opportunity to advance the frontiers of tabletop X-ray technology, contribute to bring a next-generation light source online and employ it to explore ultrafast phase transitions, Mott physics, and coupled electron–lattice dynamics in complex materials.

The successful candidate will have the opportunity to:

• Work on the optimization of high harmonic generation driven by multi-millijoule 2200 nm OPCPA.
• Design and refine a highly efficient X-ray spectrograph based on reflection zone plates.
• Generate and control ultrashort, tunable infrared pulses for time-resolved pump–probe experiments.
• Conduct time-resolved X-ray absorption spectroscopy (tr-XAS) and explore novel applications of emergent materials.
• Investigate femtosecond structural and electronic dynamics in quantum materials and 2D van der Waals systems.

This position combines instrument development and pioneering research to bring a world-class soft X-ray source to full operation and use it to tackle fundamental questions in correlated electron systems.

Requirements

Successfully completed PhD degree in physics or a related subject.

• Hands-on experience with ultrafast and nonlinear optics.
• Broad background in ultrafast optics.
• Experience in high harmonic generation in gases
• Understanding of X-ray beamline instrumentation
• Excellent communication skills, and in particular good command of the English language.
• Programming skills: Python, MATLAB, Wolfram Mathematica etc.

In addition, research experience in one of the following fields is an advantage:

• Ultrafast pulse characterization (e.g. SHG-FROG)
• Work with high vacuum (HV) setups
• Solid state physics
• CAD design (e.g. Solid edge)
• LabVIEW

We offer

• An attractive, diverse work environment and a varied role where you make an important contribution to international research.
• A position as public servant in the TVÖD-E13 payment scheme initially limited to 2 years.
• Access to world-class laboratory and analytical infrastructure.
• Modern and predominantly electronic workflows.
• Attractive and individualized training opportunities, e.g., through the Planck Academy.
• Extensive on-site technical training
• Subsidy for the job ticket.
• Very good connections to public transport, bicycle parking, charging stations for e-cars, good parking facilities.
• A friendly and respectful international working environment.
