Extended Bose-Hubbard Model

Extended Bose-Hubbard Model

We have studied the extended Bose-Hubbard Model with dipolar Er atoms as well as how the superfluid-to-Mott-insulator transition is modified by the dipole-dipole interaction.

Narrow-line magneto-optical trap for erbium

Narrow-line magneto-optical trap for erbium

We have reported on the experimental realization of a robust and efficient magneto-optical trap for erbium atoms, based on a narrow cooling transition at 583 nm.

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.
