Taming light -matter interaction on the nanometer scale

If you have a question about this talk, please contact .

Extensive research in plasmonics over the last decade has demonstrated the ability of noble metal nanostructures to concentrate optical fields down to the nanometer scale. Such control of light, well beyond the limit of diffraction, potentially opens new opportunities for enhanced interaction with tiny amounts of matter down to the single molecule/atom level. In practice though, fully exploiting the capability of plasmonics requires nanoscale positioning of the molecule/atoms within the hot spot, where the light is concentrated.

In this talk, we first present different experimental strategies to accurately control the interaction of top-down metallic nanostructures with few to single molecules or artificial atoms. We then discuss some applications to different areas including nanochemistry, biosensing and quantum information
