Supersolids are fluid and solid at the same time. In jointly collaboration work, together with Thierry Giamarchi, theoretical physicist from the University of Geneva, we have for the first time investigated what happens when such a state is brought out of balance. We discovered a soft form of solid of high interest for science. As we report in Nature Physics, we were also able to reverse the process and restore supersolidity.

Study of interspecies Feshbach resonances published in PRA

A key step in creating controlled interactions in dipolar quantum mixtures is the characterization of interspecies Feshbach resonances.
Long-lived supersolid behavior
In a joint work from the RARE and ERBIUM team as well as our theory collaborator from IQOQI, Rick van Bijnen, we have observed hallmarks of supersolidity in dipolar quantum gases of Erbium and Dysprosium. Our work is highlighted in a Viewpoint article in Physics by T. Donner.
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. The experiment has been conducted in the RARE Lab and we observe simultaneous quantum degeneracy of 5 Bose-Bose mixture and a Bose-Fermi one.
The magic of Er and Dy: magneto-optical trap with only 5 beams!
As the first result of our new Erbium-Dysprosium mixture experiment RARE, we achieved for the first time the simultaneous trapping of Erbium and Dysprosium atoms in a magneto-optical trap (MOT).
