Considering the hurdles of experiments with more than one atomic species, the temptation arises of rephrasing Arthur L. Schawlow: "Double-species Bose-Einstein condensates are condensates with one species too many". We think otherwise. Quantum mixtures allow the investigation of a wealth of genuinely quantum phenomena: mixed phases of superfluids and Mott insulators, impurities and polarons, chemistry at zero-temperature.

"Quantum Rain" in the Spotlight

Our research on the formation of arrays of quantum droplets has been featured in the Quantum Innovators special issue of Laser Physics World.


In the accompanying interview (available here), we discuss the key ideas and implications of our work. The cover image of the special issue showcases a numerical simulation of our “quantum rain” phenomenon.
