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

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.

The Dipolar Quantum Gas Group is one of the three teams composing the Innsbruck Center for Ultracold Atoms and Quantum Gases. We focus on highly magnetic Lanthanide atoms, Erbium and Dysprosium, which are a novel and powerful resource for realizing dipolar quantum matter.

The group, led by Francesca Ferlaino, is 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.

We have three experimental apparatuses. The ERBIUM machine operates on Er atoms and produced the first Er Bose-Einstein condensate and degenerate Fermi gas. The ER-DY machine is studying degenerate mixtures of two different lanthanides: Er and Dy. The T-Reqs is currently under construction and aims at studying Rydberg states of Er. A new theory sub-division within our group is under development.
