We report on nondestructive imaging of optically trapped calcium monofluoride molecules
using in situ Λ-enhanced gray molasses cooling. 200 times more fluorescence is obtained …

We experimentally investigate the dynamics of spin solitary waves (magnetic solitons) in a
harmonically trapped, binary superfluid mixture. We measure the in situ density of each …

Laser cooling based on dark states, ie states decoupled from light, has proven to be effective
to increase the phase-space density of cold trapped atoms. Dark-states cooling requires …

We report Raman sideband cooling of a single sodium atom to its three-dimensional
motional ground state in an optical tweezer. Despite a large Lamb-Dicke parameter, high …

facilitates a controlled, low-noise environment for experiments with ultracold atomic gases …

Efficient trap** and detection of single atoms in optical tweezers are important for realizing
atom arrays, a promising platform for quantum simulation and quantum information …

We demonstrate a continuously loaded Sr 88 magneto-optical trap (MOT) with a steady-state
phase-space density of 1.3 (2)× 10-3. This is 2 orders of magnitude higher than reported in …

We report on the experimental characterization of a spatially extended Josephson junction
realized with a coherently coupled two-spin-component Bose-Einstein condensate. The …
