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.
Working in ultrahigh vacuum
All our experiments are carried out at pressures of 10^(-11) mbar. In order to achieve these ultrahigh vacuums, carefully designed chambers need to be machined and assembled.
Trapping and cooling of quantum particles
In order to trap and cool Erbium and Dysprosium in magneto optical traps, we use one of their narrow-linewidth transitions. These transitions need yellow laser light for Erbium and red one for Dysprosium.
Trapping ultracold quantum particles
In order to investigate quamtumphysics, we need high power lasers to trap atoms. In our experiments we utilise for example green light to realise an optical lattice in which the atoms can be arranged on a periodic crystal structure.

Yes, it started like this with our optical table arriving under the snow…
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.
