Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Now, for the first time, the interplay between the plasmon mode and the single particle excitation within a small metal cluster has been simulated directly.
