Query: Stochastic dynamics of a few sodium atoms in a cold potassium cloud   We report on the stochastic dynamics of a few sodium atoms immersed in a cold
potassium cloud. The studies are realized in a dual-species magneto-optical
trap by continuously monitoring the emitted fluorescence of the two atomic
species. We investigate the time evolution of sodium and potassium atoms in a
unified statistical language and study the detection limits. We resolve the
sodium atom dynamics accurately, which provides a fit free analysis. This work
paves the path towards precise statistical studies of the dynamical properties
of few atoms immersed in complex quantum environments.
