Supersolids are often described using a two-fluid model, in which a superfluid component coexists with a crystalline component that behaves classically. There is a direct analogy with a standard superfluid at finite temperature, where a classical thermal fraction complements the superfluid part. However, in a supersolid all atoms share the same many-body wavefunction. How, then, can they divide into two opposing fluids? In a recent publication, we theoretically show how a single-fluid model can account for the rotational properties of a supersolid, in which a spatially varying phase is responsible for the reduced superfluid response. Our theory makes it possible to design experimental protocols to rotate annular supersolids and to excite partially quantized supercurrents, in which each atom carries less than ℏ of angular momentum.

As promised, we are back with a green MOT! While careful optimization is still needed, we are happy to report that we have now obtained a green MOT of 174Yb atoms. We are able to switch among different Yb isotopes with ease, so a 171Yb MOT is also in the workings. In the meantime, here is an absorption image of about 2 million trapped Yb atoms. While optimizing the green MOT we are planning the next steps to trap atoms in optical tweezers! |

We wish you relaxing holidays and a fantastic New Year! We created this Christmas card with our new homogeneous unitary Fermi gas in tailored optical potentials. The gas is trapped in a 3D box potential created by two DMDs shining repulsive light both in the vertical and in the horizontal directions. Each frame consist in a single-shot image of the unitary gas with sculpted optical potential with the vertical DMD, imaged with our high-resolution microscope objective. We divide each frame into 16 or 20 segments to exploit the full resolution of the optical setup to accurately reproduce the videos on our atomic display. Feliz Navidad! Buon Natale! |
