In recent experiments, an ultracold gas of dysprosium atoms (¹⁶⁴Dy) was driven into a regime where dipole-dipole interactions are expected to lead to instability and collapse. Unexpectedly, instead of collapsing, the gas formed spatially ordered structure of stable droplets with high density. We will argue that description of the droplet state requires going beyond the mean field theory and show how to incorporate realistic interatomic interactions in the model.
