Since strongly dipolar quantum gases made from lanthanide atoms were successfully brought to degeneracy 10 years ago, they have proven to be a rich source of new and fascinating phenomena arising from the long-range and anisotropic dipole-dipole interactions. Here, we will present the latest results from our erbium and dysprosium quantum gas experiments in Innsbruck. Following the recent discovery of supersolid states, we have studied its lifecycle from the formation to its death [1]. We also discuss our latest observation of supersolidity in two dimensions [2]. Finally, we investigated the properties of strongly dipolar gases within an array of two-dimensional traps [3] using Bloch oscillations and detected a transition to a stable self-focusing state which occupies only a single lattice plane, and predict the possibility of preparing dipolar solitons.
