Highlights
Green light on gold atoms
Our group discovered that laser-driven rearrangement of just a few gold atoms inside nanoscale antennas can be observed by the naked eye.Because individual atoms or molecules are 100 to 1000 times smaller than the wavelength of visible light, it is notoriously difficult to collect information about their dynamics, especially when they are embedded within larger (…)
Molecular Adlayer and the Stability of Nanoparticle-on-Mirror Plasmonic Cavities
Immense field enhancement and nanoscale confinement of light are possible within nanoparticle-on-mirror (NPoM) plasmonic resonators, which enable novel optically activated physical and chemical phenomena and render these nanocavities greatly sensitive to minute structural changes, down to the atomic scale. Although a few of these structural parameters, primarily linked to the nanoparticle and the mirror morphology, (…)
When light and atoms share a common vibe
Our group with collaboration with MIT and CEA Saclay demonstrate a state of vibration that exists simultaneously at two different times. They evidence this quantum superposition by measuring the strongest class of quantum correlations between light beams that interact with the vibration.An especially counter-intuitive feature of quantum mechanics is that a single event can exist (…)
