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

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.
First Dipolar Quantum Mixtures!
We have created for the first time a dipolar quantum mixture by combining two highly magnetic atomic species, Erbium and Dysprosium.
Observation of roton quasiparticles in Erbium
In collaboration with our theory collaborators from Innsbruck and Hannover, we have observed for the first time so-called roton quasiparticles in an ultracold bosonic gas of erbium atoms.

Our dipolar quantum gas group …
…we work with highly magnetic Erbium and Dysprosium atoms, which we cool to Nanokelvin temperatures in oder to explore the fascinating physics of the quantum world.
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.
