%X Extreme light confinement in plasmonic nanosystems enables novel applications in photonics,sensor technology, energy harvesting, biology, and quantum information processing. Fullerenesrepresent an extreme case for nanoplasmonics: they are sub-nm carbon molecules showing high-energy ultrabroad plasmon resonances, and the fundamental mechanisms driving the plasmonicresponse and the corresponding collective electron dynamics are still elusive. Here, we uncover thedominant role of electron correlations in the dynamics of the giant plasmon resonance (GPR) of thesub-nanometer system C60 by employing attosecond photoemission chronoscopy. We find acharacteristic photoemission delay of up to about 300 attoseconds that is purely induced by coherentlarge-scale electron correlations in the plasmonic potential. These results provide novel insightsinto the nature of the plasmon resonances in sub-nm systems and open new perspectives foradvancing nanoplasmonic applications.
