About the Research
The research conducted by Sjoerd Cornelis Pieter van Kooten explores the mechanisms of coherence in magnetic semiconductors subjected to resonant photoexcitation. The study investigates how a single photon can trigger the alignement of thousands of spins, magnetizing matter within 50 picoseconds, almost instantaneously, opening new perspectives for applications in ultra-fast technologies.
Invitation
Everyone is welcome to attend this important academic event and enrich the discussion on this highly relevant scientific topic.
