Dipolar Quantum Gases of Erbium Atoms 

In our ERBIUM Lab, we daily produce Bose-Einstein condensates (BEC) and degenerate Fermi gases (dFG) of strongly magnetic Er atoms, which is the last born species in the family of Bose condensed atoms. Based on the richness of Er internal level structure, we were able to devise a very simple approach to reach quantum degeneracy with this complex species. In 2012, we produced the first Er BEC and shortly after the first dFG. Er degenerate quantum gases have an extremely prominent dipolar character because of their large atomic magnetic moment, opening the possibility to study fascinating effect arising from the anisotropic and long-range dipole-dipole interaction.

Bloch oscillations and matter-wave localization in erbium!
Studying erbium atoms in a one-dimensional lattice, we utilize Bloch oscillations to evaluate the role played by the quantum fluctuations and observe an interaction-driven transition to a localized state. Additionally, we reveal the existence of lattice-bound macrodroplets and two-dimensional bright solitons.
