The spectral linewidth of an ensemble of fluorescent emitters is dictated by a combination of the single emitter linewidths and sample inhomogeneities. For semiconductor nanocrystals, efforts to tune ensemble linewidths for optical applications have

We introduce a generic solver for dynamic portfolio allocation problems when the market exhibits return predictability, price impact and partial observability. We assume that the price modeling can be encoded into a linear state-space and we demonstr

We study the effect of a dielectric interface on the emission of individual semiconductor quantum dots (QDs). By means of a simple experimental method, a single nanoparticle can be placed successively close and far from an interface, enabling a direc

We study the fluorescence patterns produced by single CdSe nanocrystals in defocused microscopy. The patterns are directly related to the structure of the nanocrystal emission dipole and their analysis provides a full determination of the three-dimen

We measure the anomalous spectral diffusion of single colloidal quantum dots over eight temporal decades simultaneously by combining single-molecule spectroscopy and photon-correlation Fourier spectroscopy. Our technique distinguishes between discret

We demonstrate the realization of a highly efficient triggered source of single photons emitted by colloidal CdSe∕ZnS nanocrystals at room temperature. Under pulsed excitation, the fluorescence of single nanocrystals excited close to saturation exh

Fluorescence spectroscopy of single chromophores immobilized on a substrate has provided much fundamental insight, yet the spectral line shapes and dynamics of single chromophores freely diffusing in solution have remained difficult or impossible to

We describe a method to probe the spectral fluctuations of a transition over broad ranges of frequencies and timescales with the high spectral resolution of Fourier spectroscopy, and a temporal resolution as high as the excited state lifetime, even i

We show that the single emitter linewidth underlying a broadened ensemble emission spectrum can be extracted from correlations among the stochastic intensity fluctuations in the ensemble spectrum. Spectral correlations can be observed at high tempora

We examine the possibility of measuring the emission linewidth $2\ensuremath{\hbar}{\ensuremath{\Gamma}}_{2}$ of a single-photon source by Michelson interferometry. Such an emitter is characterized by a limited fluorescence intensity and, when embedd
