Austrian of the Year 2024
Francesca was crowned as the ‘Austrian of the Year’ in the research category at the Austria 24 gala by Die Presse!
Summer BBQ
Our 2024 Summer BBQ took place on the 24th of June and celebrated the many different achievements of the group!
Murder Mystery Dinner
Our 2024 group dinner took place on the 18th of January at CasoinN da Giorgio restaurant, with a 1920’s Murder Mystery theme!
Glitches in supersolids: links between neutron stars and quantum matter
By emulating the connection between a rotating supersolid phase and an external solid phase, we were able to replicate “glitches” – sudden jumps in the solid angular momentum driven by quantum vortices leaving the supersolid.
Cluster of Excellence Quantum Science Austria granted
Three Clusters of Excellence in Innsbruck have been funded! With highly endowed clusters of excellence, the Austrian Science Fund FWF creates Austrian flagships of basic research. The University of Innsbruck will coordinate the Cluster of Excellence for Quantum Sciences.
Bloch Oscillations
By letting an erbium quantum droplet fall under gravity through an optical lattice, it is possible to understand the inter-atomic interactions and quantum fluctuations through variations of the Bloch oscillation.
ERC Advanced Grant DymetEr has been funded!
Our group studies dipolar quantum gases made of Erbium (Er) and Dysprosium (Dy) atoms. These extraordinarily magnetic species are a powerful new resource for reaching quantum simulation with strong connectivity, in which each atom is coupled to the other over long distances, and exploring exotic phases of matter that have no classical counterpart.
We have four labs: the ERBIUM LAB, where Er was Bose condensed for the first time ever; the Er-Dy LAB, which studies quantum dipolar mixtures under a quantum-gas microscope; the T-REQs LAB, where we trap Er atoms in arrays of optical tweezers for Rydberg physics; and the Dy-Yb LAB, currently under construction – this new experimental apparatus will be used to study many-body phases of highly-magnetic dysprosium and of mixtures with non-magnetic ytterbium. The Theory Group completes our team studying and predicting dipolar phenomena in dipolar quantum gases and mixtures.
The group, led by Francesca Ferlaino, is jointly 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, and it is part of the Innsbruck Center for Ultracold Atoms and Quantum Gases.

News from the labs
Now in Nature Physics! In collaboration with our theory collaborators from Innsbruck (Rick van Bijnen) and Hannover (Falk Wächtler and Luis Santos), we have observed for the first time so-called roton quasiparticles in an ultracold quantum gas of highly magnetic bosonic erbium.

Now in Physical Review A! In collaboration with our theory colleagues from Paris (M. Lepers, J.-F. Wyart and O. Dulieu) we have determined the dynamical polarizability of ultracold erbium atoms in the ground and in one excited state at three particular relevant wavelengths.
