Ferlaino group at the InnFi Meeting 2024

by

The Ferlaino group headed down south to Florence from October 29th to the 31st for the Ultracold Florence-Innsbruck Joint Meeting hosted at the beautiful National Institute of Optics (Istituto Nazionale di Ottica, CNR-INO).  We had a great time sharing our latest research with presentations by Elena and Eva (Theory and Er-Dy), Louis (ERBIUM) and Daniel (T-REQS)!

Vortices in a dipolar supersolid

Now published in Nature!

In an internal collaboration between the Er-Dy Lab and the Theory subgroup, our new pre-print reveals a fundamental difference in vortex nucleation between the unmodulated superfluid and the modulated 2D supersolid phase of dipolar BECs. This work builds on our previous investigation of vortices in dipolar gases (see our writeups here and here) and of supersolids with two-dimensional crystalline order (see our writeup here). This opens the door to study the hydrodynamic properties of exotic quantum systems with multiple spontaneously broken symmetries, ranging from quantum crystals to neutron stars — for a general overview of the connection between glitches in the supersolid and neutron stars, see our writeup here.
