Short presentation
Vassilios Kapaklis leads a group with a strong focus on magneto-photonics and the emergent magnetic order and dynamics of mesoscopic spin systems. The resulting materials and nano-structures have a potential for becoming functional components in future energy-efficient memory and computational architectures. The research is funded by the Knut and Alice Wallenberg Foundation, the European Commission, the Swedish Research Council, STINT and the Carl-Tryggers Foundation.
