Ralph Ernstorfer

Technische Universität Berlin is advertising a PhD position in experimental condensed matter physics within the Ultrafast Nanoscience group and the collaborative research center CRC/TRR227 “Ultrafast Spin Dynamics” . The project focuses on time- and momentum-resolved studies of electronic and spin dynamics in two-dimensional magnetic materials and their heterostructures. The successful candidate will carry out time-resolved ARPES experiments using high-harmonic generation light sources to investigate ultrafast electron, spin, exciton, and orbital dynamics. The research is aimed at understanding microscopic mechanisms relevant to future spintronic and optoelectronic devices. The position is embedded in a strong international training environment and offers the opportunity to pursue a doctorate. It is a 0.75 working-time research assistant position, funded for three years , with salary at TV-L E13 (Berliner Hochschulen). The post is in the team of Dr. Tommaso Pincelli within the group of Prof. Ralph Ernstorfer at TU Berlin. Eligibility highlights: applicants should have a Master’s degree, Diplom, or equivalent in physics or a closely related field. Good knowledge of German and/or English is required, with willingness to learn the missing language skills. Strong interest in ultrafast spectroscopy, condensed matter physics, and fundamental materials physics is expected. Helpful experience includes photoelectron spectroscopy, femtosecond lasers, ultrafast science, magnetism and spin phenomena, ultra-high vacuum technology, non-linear optics, high harmonics generation, Python, and data/control software such as LabVIEW. Application deadline: 2026-05-15. Applicants should submit a motivation letter, CV, complete publication list, and contact details of two references. Applications are to be sent to Dr. Tommaso Pincelli, quoting reference number II-49/26 , via email or the TU application portal.

Technische Universität Berlin and the Fritz Haber Institute of the Max Planck Society are advertising a PostDoc position in experimental physics within the Ultrafast Nanoscience group of Prof. Ralph Ernstorfer and Dr. William Windsor . The project focuses on femtosecond diffraction to study spin dynamics and lattice dynamics in antiferromagnets . The work will primarily use femtosecond electron diffraction at the Fritz Haber Institute and ultrafast X-ray diffraction at facilities such as BESSY II. This is a strong fit for candidates interested in condensed matter physics , ultrafast science , crystallography and diffraction methods , magnetism , and related optical/THz research. Eligibility highlights include a completed university degree (Master, Diplom or equivalent) and a PhD in physics or a closely related field with excellent academic performance. Applicants should have extensive hands-on expertise in at least one of: ultrafast optics , magnetic diffraction (X-rays or neutrons), or ultrafast electron diffraction . Good German and excellent English communication skills are required; programming skills in Matlab or Python are desirable. The position is a 2-year research associate postdoc appointment at salary grade 13 TV-L Berliner Hochschulen , with full-time employment and possible part-time arrangements. The team is described as diverse, international, and English-speaking. To apply, candidates should email a letter of motivation , CV , complete publication list , and two references to [email protected] , quoting reference number II-139/26 . The application deadline is 2026-05-08 .
