LongRange Workshop 2023
6-8.9.2023, San Sebastian (Spain). This workshop will be an opportunity to discuss recent advances on the physics of Rydberg atoms, magnetic atoms, dipolar molecules, light-induced dipoles and dipolar interactions between artificial atoms and to explore new directions.
Introductory Course on Ultracold Quantum Gases 2023
9-12.06.2023, Innsbruck. Our course will give a basic introduction into the fascinating research field of cold atoms and ultracold quantum gases, which offers many exciting opportunities for young researchers.
Summer 2023: Aurora Excellence Fellowship Program
Open call: The Aurora Excellence Fellowship Program for Visiting Bachelor, Master and PhD Students is now accepting applications.
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.
Atoms in Tweezers
In the T-REQS lab we have now loaded atoms in our optical tweezers.
Vortices in a dysprosium gas
By stirring the magnetic field which polarizes the atoms in a dysprosium condensate, we were able to generate vortices–tiny quantum tornadoes–in a dipolar gas for the first time!
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!
Happy 10th Birthday to the first Erbium BEC!
Phase coherence in out-of-equilibrium supersolid states of ultracold dipolar atoms
By quenching the contact interaction, it is possible to destroy the phase coherence in a dipolar supersolid. However, the supersolidity is “repaired” when reversing the dephasing process.
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 three 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, and the T-Reqs LAB, where we trap Er atoms in arrays of optical tweezers for Rydberg physics. Recently, we have established a theoretical subdivision aimed at 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
With collaborators from the University of Otago, we investigate the excitation spectrum and compressibility at the superfluid-to-supersolid transition point, showing that the speeds of sound and the compressibility are discontinuous at the transition.

In this paper, together with Dr. Giacomo Lamporesi at the University of Trento, we investigate more thoroughly the conditions required to generate vortices through magnetostirring, focussing on the currently experimentally accessible regime.

Together with collaborators at ICFO, Barcelona, we investigate Hubbard- Thouless pumps when including dipolar interactions. While on-site repulsion destroys the mechanism, adding non-local interactions can recover the Thouless pump mechanism …
