1/f noise for intermittent quantum dots exhibits non-stationarity and critical exponents

The power spectrum of quantum dot (QD) fluorescence exhibits $1/{{f}^{\beta }}$ noise, related to the intermittency of these nanosystems. As in other systems exhibiting $1/f$ noise, this power spectrum is not integrable at low frequencies, which appears to imply infinite total power. We report measu...
