Correlations between Subsequent Blinking Events in Single Quantum Dots

We explain the long-range correlations found by Stefani and his co-workers between blinking times of single colloidal quantum dot emission. Our explanation is based on the multiple recombination center model we recently suggested. The model produces positive correlations between subsequent-on on and off-off times and negative on-off correlations, as observed in the experiment. we also reproduce qualitatively the dependence of correlations between subsequent on-on, on-off, and off-off times on the number of switching events separating them.
