Recent experiments with Bose-Einstein condensates of dysprosium  and erbium  atoms have observed the formation of dilute quantum gas droplets that can preserve their form, even in the absence of any external confinement . These droplets occur when the long-ranged dipole-dipole interaction between the atoms dominates over the short-ranged contact interaction. In this regime meanfield theory predicts that the condensate is unstable to collapse, however the Lee-Huang-Yang quantum fluctuation corrections to the meanfield energy  can stabilize the system as one or many finite sized droplets. I will discuss our current understanding of these droplets, and introduce a new type of nonlinear Schrodinger equation used to describe their equilibrium and dynamical properties.
