ITAMP Workshop
May 10-12. 2023 – Unravelling quantum many-body physic with long-range interacting platforms
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.
TIQIT 2023
The Trento-Innsbruck Quantum Information Tour will take place from the 27th of February to the 2nd of March in Trento and Innsbruck.
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.
3D array of large-spin fermions
In joint theoretical and experimental work with our theory colleagues A.-M. Rey (JILA) and B. Zhu (ITAMP) we investigate dipolar induced magnetization-conserving spin exchange dynamics with fermionic Er in a 3D optical lattice
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 dipoalr 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.

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

Now in Science! In the presence of isotropic interactions, the Fermi surface of an ultracold Fermi gas is spherical. Introducing anisotropic interactions can deform it. This effect is subtle and challenging to observe experimentally. We report the observation of such a Fermi surface deformation in a degenerate dipolar Fermi gas of

We have studied the scattering behavior of ultracold Er atoms and observed an enormous number of Fano-Feshbach scattering resonances and demonstrate high correlation in the spectra, underlying chaotic scattering between the particles. This work, now published in NATURE, is a joint effort between our group, John L. Bohn from JILA (Boulder,
