The last 15 years has seen tremendous experimental progress for the manipulation and control of ultracold atoms with sizeable dipole-dipole interactions. In this review, together with other group leaders who first condensed dysprosium and chromium, we review the discoveries made so far, and lay out the future perspectives for this exciting field!

In the T-REQS lab we have now loaded our first Er atoms into optical tweezers! This is an significant step towards our goal of producing arrays of single atoms within tweezers which we will use to study the interactions of Rydberg atoms.
It is now an exciting time to work with ultracold highly-magnetic quantum gases, thrived by the rapid developments of quantum science based on lanthanide species. We are continually searching for outstanding Master and PhD Students!
Our review on the quantum many-body physics in ultracold magnetic lanthanides is now published in Nature Physics!

After several months of preparations and setting up our system, we have produced our first ultracold atomic cloud of erbium atoms in our new T-REQS lab. After initial slowing down in a Zeeman slower with a broad transition, we trap and cool 166Er atoms in a 5 beam magneto-optical trap operating on the narrow linewidth transition at 583nm. We trap up to 120 million atoms and cool them to ~15 microkelvin in a compressed MOT phase. This is a first step on our way to trapping ultracold erbium atoms in optical tweezers.
Applications have now opened for the Introductory Course on Ultracold Quantum Gases 2022 winter school. This will take place in Innsbruck between the 9th and 11th February 2022. Please visit the website for more information and to apply.
