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.

News from the labs
Our publication on the first-time observation of roton quasiparticles in quantum gases was chosen by the editors of Nature Physics as one of their favorite papers of the past 15 years. To mark the anniversary of the journal, the most important works in the various disciplines of physics are presented.

Congratulation to Lauriane Chomaz on the publication of her paper in Phys. Rev. A. In this work, Lauriane investigates the general relationships existing between the density contrast, the superfluid fraction, and the response to a high-energy scattering probe of density-modulated states within a classical-field approach.

Group news
Now in Measurement Science and Technology! In collaboration with our theory colleague at IQOQI (Rick van Bijnen) we present a novel method for the analysis of quantum gas microscope images. Our method uses deep learning to improve the fidelity with which lattice sites can be classified as occupied or unoccupied.
