A new spin in nano-electronics
In recent years, electronic data processing has been evolving in one direction only: The industry has downsized its components to the nanometer range. But this process is now reaching its physical limits. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Paul Scherrer Institut (PSI) are therefore exploring spin waves or so-called magnons – a promising alternative for transporting information in more compact microchips. Cooperating with international partners, they have successfully generated and controlled extremely short-wavelength spin waves. The physicists achieved this feat by harnessing a natural magnetic phenomenon, as they explain in the journal Nature Nanotechnology.
Condensed Matter Theory Group
The activities of the Condensed Matter Theory (CMT) group focus on both applied and fundamental topics in condensed matter physics, material science, and the biological sciences. Aside from pursuing its own research, CMT provides theoretical support to experiments done at PSI. Particular interests include frustrated magnetism, disordered and/or strongly correlated systems, quantum dynamics and transport, plasticity, and the principles governing bio-molecules.
