In the Sr Rydberg lab, we have successfully trapped individual Strontium atoms using a one-dimensional array of optical tweezers. The video demonstrates a sequence of experimental cycles, during which the presence of atoms is detected via fluorescence imaging. After loading multiple atoms in each optical tweezer, the occupancy is reduced to either zero or one atom exploiting a light-assisted collision mechanism which expels pairs of atoms. On average, we achieve 40% single-atom occupancy, with atoms randomly distributed across the array, as shown in the video. This work is a significant step towards the preparation of defect-free arrays of single atoms in optical tweezers, which will be the starting point for future quantum simulation experiments.

We have completed the optical setup for a 461 nm laser source that will be employed for slowing down, capturing in a 3D MOT and imaging Strontium atoms in the FloRydberg platform.

Blue MOT, we will be there soon!

We finished the assembly and baking of a really compact ultra-high vacuum apparatus.

Ready to host Strontium atoms!.
