ERBIUM NEWS

We report on the achievement of Bose-Einstein condensation of erbium atoms and on the observation of magnetic Feshbach resonances at low magnetic fields. By means of evaporative cooling in an optical dipole trap, we produce pure condensates of Er168, containing up to 7×104 atoms. Feshbach spectroscopy reveals an extraordinary rich loss spectrum with six loss resonances already in a narrow magnetic-field range up to 3 G. Finally, we demonstrate the application of a low-field Feshbach resonance to produce a tunable dipolar Bose-Einstein condensate and we observe its characteristic d-wave collapse. [more]

Crossover from a BEC to a macrodroplet

Together with our theory colleagues from Hannover, we have investigated the formation of a macrodroplet state in an ultracold bosonic gas of erbium atoms.

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.

The Dipolar Quantum Gas Group is one of the three teams composing the Innsbruck Center for Ultracold Atoms and Quantum Gases (AG Ferlaino/Grimm/Nägerl) and focuses on ultracold strongly magnetic Lanthanide atoms, which are a novel and powerful resource for realizing dipolar quantum matter.

The group, led by Francesca Ferlaino, is located at the  Institute for Experimental Physics (IExP) of the University of Innsbruck and at the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences.
