Abstract
Section titled āAbstractāNanoscale control over the second-order photon correlation function <em>g</em><sup>(2)</sup>(Ļ) is critical to emerging research in nonlinear nanophotonics and integrated quantum information science. Here we report on quasiparticle control of photon bunching with <em>g</em><sup>(2)</sup>(0) > 45 in the cathodoluminescence of nanodiamond nitrogen vacancy (NV<sup>0</sup>) centers excited by a converged electron beam in an aberration-corrected scanning transmission electron microscope. Plasmon-mediated NV<sup>0</sup> cathodoluminescence exhibits a 16-fold increase in luminescence intensity correlated with a threefold reduction in photon bunching compared with that of uncoupled NV<sup>0</sup> centers. This effect is ascribed to the excitation of single temporally uncorrelated NV<sup>0</sup> centers by single surface plasmon polaritons. Spectrally resolved Hanbury Brown-Twiss interferometry is employed to demonstrate that the bunching is mediated by the NV<sup>0</sup> phonon sidebands, while no observable bunching is detected at the zero-phonon line. As a result, the data are consistent with fast phonon-mediated recombination dynamics, a conclusion substantiated by agreement between Bayesian regression and Monte Carlo models of superthermal NV<sup>0</sup> luminescence.
