The onset of microscopic superfluidity has been reported in ultracold droplets of bosons (4He atoms or para-H2 molecules) containing a variety of molecular dopants. The physics of these droplets involve both Bose-Einstein condensation (BEC) and superfluidity. The two phenomena, while closely related, are not exactly the same. Superfluidity is fundamentally a microscopic effect and thermodynamic limit is necessary; it is still remarkable, though, that the signature of superfluidity has been reported in doped droplets consisting of as few as 4 4He atoms. The studies presented here adopt a molecular vantage point to investigate the quantum mechanics …
