| Abstract: | We propose a microscopic quantum-mechanical model for describing the nonstochastic dynamics of the nanoscopic light-emissive quantum dot. The model is extended beyond a single quantum dot to consider the Coulomb repulsion between neighboring quantum dots in the ionic states caused by the random fluctuations of charge carriers. We find that the interaction gives rise to intensified blinking intermittency, continuous memory loss of the dynamics, and fluorescence enhancement in an ensemble of light-emissive quantum dots, which explains the recent experimental results. Our findings clarify the nature of the interaction underlying in the ensemble. |
