ERBIUM NEWS:
Now in PRX! We show that for ultracold magnetic lanthanide atoms (Er and Dy) chaotic scattering emerges due to a combination of anisotropic interaction potentials and Zeeman coupling under an external magnetic field. The scattering is studied in a collaborative experimental and theoretical effort, involving our group, the Stuttgart Dy Group led by T. Pfau and the theory colleagues S. Kotochigova and E. Tiesinga in the USA. [more]

Now in PRL! We created a novel type of dipolar system made of two ultracold bosonic dipolar atoms bounded into a molecules. This work is the result of a combined experimental and theoretical effort between our group, the cold collisions group at LAC in France, and the theory group at Temple University (USA). [more]

We report on the observation of a large anisotropy in the rethermalization dynamics of an ultracold dipolar Fermi gas driven out of equilibrium. Our system consists of an ultracold sample of strongly magnetic Er167 fermions, spin polarized in the lowest Zeeman sublevel. In this system, elastic collisions arise purely from universal dipolar scattering. Based on cross-dimensional rethermalization experiments, we observe a strong anisotropy of the scattering, which manifests itself in a large angular dependence of the thermal relaxation dynamics. Our result is in good agreement with recent theoretical predictions. Furthermore, we measure the rethermalization rate as a function of temperature for different angles and find that the suppression of collisions by Pauli blocking is not influenced by the dipole orientation.[more]
