Atoms trapped in metasurface tweezer arrays

Apr 30, 2024

In collaboration with the Nanfang Yu Lab at Columbia, we have developed a technique to trap atoms in optical tweezer arrays, generated via holographic metasurfaces. The picture shows a flouresence image of about 200 Sr atoms with a mean spacing of 3 um, cooled and trapped in a metasurface tweezer array. Atom arrays with arbitrary geometry can be created with this technique. Congrats to the entire TweeSr and Yu Lab Team on this wonderful achievement!
