Researchers at Brown and the group led by Niek van Hulst report in Nature Comm. on magnetic components in light-matter interactions.
July 31, 2012
Former ICFOnian Dr. Tim Taminiau and Dr. Sinan Karavelli, both at Brown University (USA), have recently reported in Nature Communications about the magnetic nature of light emission. The results introduce a new tool: an atomic scale system that interacts with the magnetic component of light.
Light-matter interactions are generally dominated by electric fields and electric dipole transitions. In this study, however, the authors manage to quantify magnetic contributions to light emission, and exploit the strong natural magnetic dipole transitions in lanthanide ions to measure optical-frequency magnetic fields.
