We offer a position in experimental condensed matter physics, focusing on the investigation of ultrafast spin–lattice coupling and the exchange of energy and angular momentum between spins and phonons in magnetic materials. A central goal is to clarify the role of chiral phonons in demagnetization and their transport in heterostructures. The research will in particular address 2D van der Waals magnets, magnetic oxides, and rare-earth materials.The project is part of the Collaborative Research Center 'Ultrafast Spin Dynamics' (TRR 227) and employs a range of ultrafast experimental techniques, with femtosecond electron diffraction in our laboratories at the Fritz Haber Institute of the Max Planck Society in Berlin-Dahlem serving as the primary method. The project will be carried out in the internationally oriented team of Dr. William Windsor within the group "Ultrafast Nanoscience” led by Prof. Ralph Ernstorfer.

Experimental work is done in a team environment. The applicant is then expected to pursue their research work independently.

• Conduct ultrafast experiments in the group’s labs on the candidate’s defined research topic
• Take part in the team’s experiments (locally and in international facilities)
• Pursue independent research on acquired results: data analysis, interpretation, communication (e.g. publications) , presentation (international conferences)

• Successfully completed university degree (Master, Diploma or equivalent) in physics or a very related field
• Very good communication skills in English (verbal and written), good German language skills are an advantage.
• Ability to work independently as well as in a team environment.
• Programming skills: Matlab, Python etc.

We are looking for highly motivated, curious, and enthusiastic, researchers with very good academic records and strong interests in fundamental materials’ physics, ultrafast science, and their potential intersection. BSc or MSc level research experience in one of the following fields is an advantage:

• Crystallography and diffraction methods (X-ray, electrons, or Neutrons)
• Femtosecond lasers or ultrafast science
• Magnetism
• Optical or phonon-related studies

Interested candidates are requested to send a letter of motivation, a CV and a complete list of publications together with the contact details of two references to Dr. William Windsor ( windsor@tu-berlin.de ), quoting the reference number in the E-mail subject.
