Spin+X supports Ukrainian scientists
Spin+X offers support to scientists from Ukraine who have been directly affected by the war. An eligible candidate should propose a contribution relevant to the research conducted within Spin+X. If you are a Spin+X scholar interested in this call, please contact the Spin+X office and outline the science relevant to Spin+X you are proposing and the support you would like to receive. In addition, we especially encourage students from Ukraine who are pursuing a Master's or PhD program to contact us.
Spin+X - Spin in its collective environment
The Transregional Collaborative Research Center 173 Spin+X investigates spin properties from various perspectives and by connecting several scientific disciplines. Its research encompasses the whole range of spin research spanning from microscopic properties, to emergent spin phenomena and to the coupling to the macroscopic world. This constitutes a new discipline that we refer to as Advanced Spin Engineering, which seeks to create new functionalities based on spin physics. Spin+X builds on an outstanding research infrastructure in physics and chemistry at RPTU and JGU, as well as in engineering at RPTU, which are at the forefront of spin-related science and technology.

SPIN+X PhD student wins oral presentation award at SPIE Photonics West
At the world's largest annual event for the photonics, laser, and biomedical optics industries, the SPIE Photonics West in San Fransico, SPIN+X PhD student Sebastian Weber has won the student oral presentation award in the conference Laser Applications in Microelectronic and Optoelectronic Manufacturing (LAMOM) XXIII. Sebastian Weber is a PhD student in the group of SPIN+X PI Bärbel Rethfeld in the project A08 „Exchange interaction on femtosecond time scales“.
In his talk with the title „Electron dynamics in silver after ultrafast laser-excitation“ the dynamics of nonequilibrium electrons in noble metals after excitation with an ultrashort laser pulse has been presented. Such femtosecond laser pulses drive the electrons out of thermal equilibrium. The time evolution of the energy distribution has to be described with numerically expensive kinetic models, going far beyond temperature-based equations. In the work, the timescales of the relaxation processes have been analyzed as well as the influence of the nonequilibrium state on the further energy dissipation. The results are important for the understanding of the optical excitation of metals as well as the spin-dependent electron dynamics in ferromagnets.
