In a combined theory and experimental work, we study the elementary excitations of trapped dipolar quantum gases crossing from regular superfluid to supersolid. Our work is now published in PRL and summarized in the Synopsis by Sophia Chen.
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.
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.
