Theory of Spin Systems

We are thrilled to be part of the recently launched German priority program, ‘SPP 2558: Unconventional Magnetism’ and look forward to working together with the scientific community. At the same time, we re-welcome Jannik Ockenfels in the group, now as a PhD student. Jannik will lead our group's contributions to the priority program.

We are delighted that our article, ‘Unquenched orbital angular momentum as the origin of spin inertia’ is now published in Physical Review B. A big congratulations and thanks to Tarek, who led the work, Darpa as well as our external collaborator Ritwik Mondal (IIT Dhanbad).

Excited that our collaborative article, ‘Twist-tuned exchange and hysteresis in a bilayer van der Waals magnet,’ is now published in Nature Communications. Thanks to our colleagues from TU Darmstadt, NIMS - Tsukuba, and UCT - Prague for their valuable contributions and making this work possible. A special congratulations and thanks to our (former) postdoc Sonu, who led the theoretical efforts, and to Priyanka and Wenze from the Urbaszek group at TU Darmstadt for leading the experiments and the project.

Thrilled that our collaborative review article, 'Excitons in van der Waals magnetic materials,' is now published in Nature Materials. A special thanks to the colleagues at CUNY (who anchored this work), TU Munich, National Laboratory of the Rockies, and the University of Washington for making it possible and the enriching collaboration.

David-Leon Osifo has joined the group as a research assistant. He is a bachelor student in our department and will work with us on discovering new spin textures in two-dimensional magnets. Welcome David!

Jonas Leidner has completed his master program with an excellent thesis entitled “Magnetoelastic interactions uncovered using the spin-pair model.” Congratulations on this milestone, Jonas! We wish you all the best for your future and hope to keep in touch.
