Description

Recent experiments with the highly magnetic atoms dysprosium and erbium have revealed the formation of a novel form of ultra-dilute stable droplets in dipolar Bose-Einstein condensates (BEC). This surprising result has been explained by the stabilization given by quantum fluctuations.
We will discuss the effects of these beyond-mean-field corrections of a dipolar BEC in three dimensions as well as in a quasi-one-dimensional geometry.
Moreover, we will show that the same arguments can be applied to a system of a mixture of two different bosons in absence of atomic dipoles but with different inter- and intra-coupling constants.
