Vortices in a dysprosium gas

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

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.

Phase coherence in out-of-equilibrium supersolid states of ultracold dipolar atoms

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.

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

Excitation spectrum of a trapped dipolar supersolid

Excitation spectrum of a trapped dipolar supersolid

In a combined theory and experimental work, we study the elementary excitations of trapped dipolar quantum gases crossing from regular superfluid to supersolid.

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

Studying erbium atoms in a one-dimensional lattice, we utilize Bloch oscillations to evaluate the role played by the quantum fluctuations and observe an interaction-driven transition to a localized state. Additionally, we reveal the existence of lattice-bound macrodroplets and two-dimensional bright solitons.
