Abstract
We investigate the statistics of photons emitted by tunneling electrons in a single electronic level plasmonic nanojunction. We compute the waiting-time distribution of successive emitted photons . When the cavity damping rate is larger than the electronic tunneling rate , we show that in the photon-antibunching regime, indicates that the average delay time between two successive photon-emission events is given by . This is in contrast with the usually considered second-order correlation function of emitted photons, , which displays the single timescale . Our analysis shows a relevant example for which gives independent information on the photon-emission statistics with respect to , leading to physical insight into the problem. We discuss how this information can be extracted from experiments even in the presence of a nonperfect photon-detection yield.
