Theoretical Condensed Matter Physics - Student at CFEL, Hamburg

PhD position in theoretical physics

We invite applications for a PhD position in theoretical physics (with the focus on code development) within the project on the interaction of x-ray radiation from free-electron laser with solids.

Free-electron lasers (FELs) opened new horizons in studying ultrafast transitions in matter. Experiments performed in a pump-probe scheme enable studying the progress of the transitions in time. Such experiments require an accurately characterized FEL pulse and its precise timing to an external optical laser. Non-invasive timing tools based on recording the transient optical properties have been already proposed. However, in thex-rayregimesuch measurementsare affected by electron transport outof the interaction region - electronic diffusion. The aim of this project is to investigate the diffusion effect in detail, in order to increase the resolution and the reliability of x-ray pulse detection. This would enable a comprehensive temporal and spatial characteristics of x-ray pulses. This project will be performed in a close collaboration with experimental groups. Dedicated measurements are planned at the FLASH facility at DESY, Hamburg to verify model predictions.

Interested candidates with excellent grades holding a Master Degree or equivalent in theoretical physics are invited to apply. Good programming skills, proven experience in analytical calculations, good knowledge of English and a solid mathematical background are expected. Applications (in English) including: (i) curriculum vitae, (ii) list of publications, (iii) copies of academic certificates, (iv) two letters of reference should be sent per electronic mail to:
